The numerical value of R is the average annual sum of El30 for storm events during a rainfall record of at least 22 years. "lsoerodent" maps were developed based on R values calculated for more than 1000 locations in 3 the Western U.S. Refer to the link below to determine the R factor for the project site. 4 htt12://cf12 u b. e12a.gov/n Qd es/sto rmwater/L EW/lewCal culator.cfm 5 R Factor Value 30 6 B) K Factor Cweiahted averaae, by area, for all site soils) The soil-erodibility factor K represents: (1) susceptibility of soil or surface material to erosion, (2) transportability of the sediment, and (3) the amount and rate of runoff given a particular rainfall input, as measured under a standard condition. Fine-textured soils that are high in clay have low K values (about 0.05 to 0.15) because the particles are resistant to detachment. Coarse-textured soils, such as sandy soils, also have low K values (about 0.05 to 0.2) because of high infiltration resulting in low runoff even though these particles are easily detached. Medium-textured soils, such as a silt loam, have moderate K values (about 0.25 to 0.45) because they are moderately susceptible to particle detachment and they produce runoff at moderate rates. Soils having a high silt content are especlally susceptible to erosion and have high K values, which can exceed 0.45 and can be as large as 0.65. Silt-size particles are easily detached and tend to crust, producing high rates and large volumes of runoff. Use Site-specific data must 7 be submitted. 8 Site-sgecific K factor guidance 9 K Factor Value 0.1 10 C) LS Factor (weiahted average, by area, for all slopes) The effect of topography on erosion is accounted for by the LS factor, which combines the effects of a hillslope-length factor, L, and a,hillslope-gradient factor, £. Generally speaking, as taillslope length and/or hillslope gradient increase, soil loss increases. As hillslope length increases, total soil loss and soil loss per unit area increase due to the progressive accumulation of runoff in the downslope direction. As the hillslope gradient increases, the velocity and erosivity of runoff increases. Use the LS table located in separate tab of this spreadsheet to determine LS factors. 11 Estimate the weighted LS for the site prior to construction. 12 LS Table 13 LS Factor Value 0.1 '14 15 Watershed Erosion Estimate (=RxKxLS) in tons/acre 0.3 16 Site Sediment Risk Factor 17 Low Sediment Risk: < 15 tons/acre 18 Medium Sediment Risk: >=15 and <75 tons/acre Low 19 High Sediment Risk: >:::: 75 tons/acre 20 PA2017-045 Receiving Water (RW) Risk Factor Worksheet Entry Score A.

The purpose is to reduce the amount and duration of soil exposed to erosion by wind, rain, runoff, and vehicle tracking, and to perform the construction activities and control practices in accordance with the planned schedule. Suitable Applications Proper sequencing of construction activities to reduce erosion potential should be incorporated into the schedule of every construction project especially during rainy season. Use of other, more costly yet less effective, erosion and sediment control BMPs may often be reduced through proper construction sequencing. Limitations • Environmental constraints such as nesting season prohibitions reduce the full capabilities of this BMP. Implementation • Avoid rainy periods. Schedule major grading operations during dry months when practical. Allow enough time before rainfall begins to stabilize the soil with vegetation or physical means or to install sediment trapping devices. • Plan the project and develop a schedule showing each phase of construction.

Sequence trenching activities so that most open portions are closed before new trenching begins. Incorporate staged seeding and re-vegetation of graded slopes as work progresses. Schedule establishment of permanent vegetation during appropriate planting time for specified vegetation. • Non-active areas should be stabilized as soon as practical after the cessation of soil disturbing activities or one day prior to the onset of precipitation. • Monitor the weather forecast for rainfall. • When rainfall is predicted, adjust the construction schedule to allow the implementation of soil stabilization and sediment treatment controls on all disturbed areas prior to the onset of rain. • Be prepared year round to deploy erosion control and sediment control BMPs. Erosion may be caused during dry seasons by un-seasonal rainfall, wind, and vehicle tracking. Keep the site stabilized year round, and retain and maintain rainy season sediment trapping devices in operational condition. • Apply permanent erosion control to areas deemed substantially complete during the project's defined seeding window. Costs Construction scheduling to reduce erosion may increase other construction costs due to reduced economies of scale in performing site grading. The cost effectiveness of scheduling techniques should be compared with the other less effective erosion and sedimentation controls to achieve a cost effective balance.

Limitations • Gravel berms may be difficult to remove. • Removal problems limit their usefulness in landscaped areas. • Gravel bag berm may not be appropriate for drainage areas greater than 5 acres. • Runoff will pond upstream of the berm, possibly causing flooding if sufficient space does not exist. • Degraded gravel bags may rupture when removed, spilling contents. • Installation can be labor intensive. • Durability of gravel bags is somewhat limited and bags may need to be replaced when installation is required for longer than 6 months. · • Easily damaged by construction equipment. • When used to detain concentrated flows, maintenance requirements increase. Implementation General A gravel bag berm consists of a row of open graded gravel-filled bags placed on a level contour. When appropriately placed, a gravel bag berm intercepts and slows sheet flow runoff, causing temporary ponding. The temporary ponding allows sediment to settle. The open graded gravel in the bags is porous, which allows the ponded runoff to flow slowly through the bags, releasing the runoff as sheet flows. Gravel bag berms also interrupt the slope length and thereby reduce erosion by reducing the tendency of sheet flows to concentrate into rivulets, which erode rills, and ultimately gullies, into disturbed, sloped soils. Gravel bag berms are similar to sand bag barriers, but are more porous. Generally, gravel bag berms should be used in conjunction with temporary soil stabilization controls up slope to provide effective erosion and sediment control. Design and Layout • Locate gravel bag berms on level contours. • When used for slope interruption, the following slope/sheet flow length combinations apply: Slope inclination of 4:1 (H:V) or flatter: Gravel bags should be placed at a maximum interval of 20 ft, with the first row near the slope toe. Slope inclination between 4:1 and 2:1 (H:V): Gravel bags should be placed at a maximum interval of 15 ft. (a closer spacing is more effective), with the first row near the slope toe. May 2011 California Stormwater BMP Handbook Portal Construction www.casqa.org 2 of 4 PA2017-045 Grallel Bag .13erm SE-6 Slope inclination 2:1 (H:V) or greater: Gravel bags should be placed at a maximum interval of 10 ft. (a closer spacing is more effective), with the first row near the slope toe. • Turn the ends of the gravel bag barriers up slope to prevent runoff from going around the berm. • Allow sufficient space up slope from the gravel bag berm to allow ponding, and to provide room for sediment storage. • For installation near the toe of the slope, gravel bag barriers should be set back from the slope toe to facilitate cleaning. Where specific site conditions do not allow for a set-back,the gravel bag barrier may be constructed on the toe of the slope. To prevent flows behind the barrier, bags can be placed perpendicular to a berm to serve as cross barriers. • Drainage area should not exceed 5 acres. • In Non-Traffic Areas: Height ::::: 18 in. maximum Top width = 24 in. minimum for three or more layer construction Top width ::::: 12 in. minimum for one or two layer construction Side slopes::::: 2:1 (H:V) or flatter • In Construction Traffic Areas: Height = 12 in. maximum Top width ::::: 24 in. minimum for three or more layer construction. Top width = 12 in. minimum for one or two layer construction. Side slopes= 2:1 (H:V) or flatter. • Butt ends of bags tightly. • On multiple row, or multiple layer construction, overlap butt joints of adjacent row and row beneath. • Use a pyramid approach when stacking bags. Materials • Bag Material: Bags should be woven polypropylene, polyethylene or polyamide fabric or burlap, minimum unit weight of 4 ounces/yd2, Mullen burst strength exceeding 300 lb/in2 in conformance with the requirements in ASTM designation D3786, and ultraviolet stability exceeding 70% in conformance with the requirements in ASTM designation D4355. May 2011 California Stormwater BMP Handbook Portal Construction www.casqa.org 3 of 4 PA2017-045 Gravel Bag Berm SE-6 • Bag Size: Each gravel-filled bag should have a length of 18 in., width of 12 in., thickness of 3 in., and mass of approximately 33 lbs. Bag dimensions are nominal, and may vary based on locally available materials. • Fill Material: Fill material should be 0.5 to 1 in. crushed rock, clean and free from clay, organic matter, and other deleterious material, or other suitable open graded, non-cohesive, porous gravel. Costs Material costs for gravel bags are average and are dependent upon material availability. $2.50- 3.00 per filled gravel bag is standard based upon vendor research. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Gravel bags exposed to sunlight will need to be replaced every two to three months due to degrading of the bags. • Reshape or replace gravel bags as needed. • Repair washouts or other damage as needed. • Sediment that accumulates in the BMP should be periodically removed in order to maintain BMP effectiveness. Sediment should be removed when the sediment accumulation reaches one-third of the barrier height. • Remove gravel bag berms when no longer needed and recycle gravel fill whenever possible and properly dispose of bag material. Remove sediment accumulation and clean, re-grade, and stabilize the area. References Handbook of Steel Drainage and Highway Construction, American Iron and Steel Institute, 1983.

A stabilized construction access is defined by a point of entrance/ exit to a construction site that is stabilized to reduce the tracking of mud and dirt onto public roads by construction vehicles. Suitable Applications Use at construction sites: • Where dirt or mud can be tracked onto public roads. • Adjacent to water bodies. • Where poor soils are encountered. • Where dust is a problem during dry weather conditions. Limitations • Entrances and exits require periodic top dressing with additional stones. • This BMP should be used in conjunction with street sweeping on adjacent public right of way. • Entrances and exits should be constructed on level ground only. • Stabilized construction entrances are rather expensive to construct and when a wash rack is included, a sediment trap of some kind must also be provided to collect wash water runoff.

The purpose of a stabilized construction entrance is to reduce or eliminate the tracking of sediment onto public rights of way or streets. Reducing tracking of sediments and other pollutants onto paved roads helps prevent deposition of sediments into local storm drains and production of airborne dust. Where traffic will be entering or leaving the construction site, a stabilized construction entrance should be used. NPDES permits require that appropriate measures be implemented to prevent tracking of sediments onto paved roadways, where a significant source of sediments is derived from mud and dirt carried out from unpaved roads and construction sites. Stabilized construction entrances are moderately effective in removing sediment from equipment leaving a construction site. The entrance should be built on level ground. Advantages of the Stabilized Construction Entrance/Exit is that it does remove some sediment from equipment and serves to channel construction traffic in and out of the site at specified locations. Efficiency is greatly increased when a washing rack is included as part of a stabilized construction entrance/exit. Design and Layout • Construct on level ground where possible. • Select 3 to 6 in. diameter stones. • Use minimum depth of stones of 12 in. or as recommended by soils engineer. • Construct length of 50 ft or maximum site will allow, and 10 ft minimum width or to accommodate traffic. • Rumble racks constructed of steel panels with ridges and installed in the stabilized entrance/exit will help remove additional sediment and to keep adjacent streets clean. • Provide ample turning radii as part of the entrance. • Limit the points of entrance/exit to the construction site. • Limit speed of vehicles to control dust. • Properly grade each construction entrance/exit to prevent runoff from leaving the construction site. • Route runoff from stabilized entrances/ exits through a sediment trapping device before discharge. • Design stabilized entrance/exit to support heaviest vehicles and equipment that will use it. July 2012 California Stormwater BMP Handbook Construction www.casqa.org 2 of 6 PA2017-045 Sta.bilized Construction Entrance/Exit TC-1 • Select construction access stabilization (aggregate, asphaltic concrete, concrete) based on longevity, required performance, and site conditions. Do not use asphalt concrete (AC) grindings for stabilized construction access/roadway. • If aggregate is selected, place crushed aggregate over geotextile fabric to at least 12 in. depth, or place aggregate to a depth recommended by a geotechnical engineer. A crushed aggregate greater than 3 in. but smaller than 6 in. should be used. • Designate combination or single purpose entrances and exits to the construction site. • Require that all employees, subcontractors, and suppliers utilize the stabilized construction access. • Implement SE-7, Street Sweeping and Vacuuming, as needed. • All exit locations intended to be used for more than a two-week period should have stabilized construction entrance/exit BMPs. Inspection and Maintenance • Inspect and verify that activity~based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMPs are under way, inspect BMPs in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Inspect local roads adjacent to the site daily. Sweep or vacuum to remove visible accumulated sediment. • Remove aggregate, separate and dispose of sediment if construction entrance/exit is clogged with sediment. • Keep all temporary roadway ditches clear. • Check for damage and repair as needed. • Replace gravel material when surface voids are visible. • Remove all sediment deposited on paved roadways within 24 hours. • Remove gravel and filter fabric at completion of construction Costs Average annual cost for installation and maintenance may vary from $1,200 to $4,800 each, averaging $2,400 per entrance. Costs will increase with addition of washing rack, and sediment trap. With wash rack, costs range from $1,200 -$6,000 each, averaging $3,600 per entrance.

July 2012 California Stormwater BMP Handbook Construction www.casqa.org 3 of 6 PA2017-045 Wind Erosion Control Description and Purpose Wind erosion or dust control consists of applying water or other chemical dust suppressants as necessary to prevent or alleviate dust nuisance generated by construction activities. Covering small stockpiles or areas is an alternative to applying water or other dust palliatives. California's Mediterranean climate, with a short "wet" season and a typically long, hot "dry" season, allows the soils to thoroughly dry out. During the dry season, construction activities are at their peak, and disturbed and exposed areas are increasingly subject to wind erosion, sediment tracking and dust generated by construction equipment. Site conditions and climate can make dust control more of an erosion problem than water based erosion. Additionally, many local agencies, including Air Quality Management Districts, require dust control and/or dust control permits in order to comply with local nuisance laws, opacity laws (visibility impairment) and the requirements of the Clean Air Act. Wind erosion conh·ol is required to be implemented at all construction sites greater than 1 acre by the General Permit. Suitable Applications Most BMPs that provide protection against water-based erosion will also protect against wind-based erosion and dust control requirements required by other agencies will generally meet wind erosion control requirements for water quality protection. Wind erosion control BMPs are suitable during the following construction activities: May 2011 California Stormwater BMP Handbook Construction www .casqa.org WE-1 Categories EC Erosion Control SE Sediment Control TC Tracking Control WE Wind Erosion Control NS Non-Stormwater Management Control WM Waste Management and Materials Pollution Control Legend: 0 Primary Category ~ Secondary Category Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease Organics Potential Alternatives EC-5 Soil Binders ~ 0 Jf User/Subscriber modifies this fact sheet in any way, the CASQA name/logo and footer below must be removed from each page and not appear on the modified version.

Selected chemical dust control agents should be environmentally benign. • Effectiveness of controls depends on soil, temperature, humidity, wind velocity and traffic. • Chemical dust suppression agents should not he used within 100 feet of wetlands or water bodies. • Chemically treated subgrades may make the soilwater repellant, interfering with long-term infiltration and the vegetation/re-vegetation of the site. Some chemical dust suppressants may be subject to freezing and may contain solvents and should be handled properly. • In compacted areas, watering and other liquid dust control measures may wash sediment or other constituents into the drainage system. • If the soil surface has minimal natural moisture, the affected area may need to be pre-wetted so that chemical dust control agents can uniformly penetrate the soil surface. Implementation Dust Control Practices Dust control BMPs generally stabilize exposed surfaces and minimize activities that suspend or track dust particles. The following table presents dust control practices that can be applied to varying site conditions that could potentially cause dust. For heavily traveled and disturbed areas, wet suppression (watering), chemical dust suppression, gravel asphalt surfacing, temporary gravel construction entrances, equipment wash-:out areas, and haul truck covers can be employed as dust control applications. Permanent Ortemporary vegetation and mulching can be employed for areas of occasional or no construction traffic. Preventive measures include minimizing surface areas to be disturbed, limiting onsite vehicle traffic to 15 mph or less, and controlling the number and activity of vehicles on a site at any given time. May 2011 California Stormwater BMP Handbook Construction www.casqa.org 2 of 5 PA2017-045 Wind Erosion Control WE-1 Chemical dust suppressants include: mulch and fiber based dust palliatives (e.g. paper mulch with gypsum binder), salts and brines (e.g. calcium chloride, magnesium chloride), non- petroleum based organics (e.g. vegetable oil, lignosulfonate), petroleum based organics (e.g. asphalt emulsion, dust oils, petroleum resins), synthetic polymers (e.g. polyvinyl acetate, vinyls, acrylic), clay additives (e.g. bentonite, montimorillonite) and electrochemical products (e.g. enzymes, ionic products).

Non-potable water should not be conveyed in tanks or drain pipes that will be used to convey potable water and there should be no connection between potable and non-potable supplies. Non-potable tanks, pipes, and other conveyances should be marked, "NON-POTABLE WATER-DO NOT DRINK." • Pave or chemically stabilize access points where unpaved traffic surfaces adjoin paved roads. • Provide covers for haul trucks transporting materials that contribute to dust. • Provide for rapid clean up of sediments deposited on paved roads. Furnish stabilized construction road entrances and wheel wash areas. • Stabilize inactive areas of construction sites using temporary vegetation or chemical stabilization methods. For chemical stabilization, there are many products available for chemically stabilizing gravel roadways and stockpiles. If chemical stabilization is used, the chemicals should not create any adverse effects on stormwater, plant life, or groundwater and should meet all applicable regulatory requirements. Costs Installation costs for water and chemical dust suppression vary based on the method used and the length of effectiveness. Annual costs may be high since some of these measures are effective for only a few hours to a few days. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Check areas protected to ensure coverage. • Most water-based dust control measures require frequent application, often daily or even multiple times per day. Obtain vendor or independent information on longevity of chemical dust suppressants.

These practices can reduce or eliminate non-stormwater discharges. Suitable Applications Water conservation practices are suitable for all construction sites where water is used, including piped water, metered water, trucked water, and water from a reservoir. Limitations • None identified. Implementation • Keep water equipment in good working condition. • Stabilize water truck filling area. • Repair water leaks promptly. • Washing of vehicles and equipment on the construction site is discouraged. • Avoid using water to clean construction areas. If water must be used for cleaning or surface preparation, surface should be swept and vacuumed first to remove dirt. This will minimize amount of water required.

January 2011 California Stormwater BMP Handbook Construction www.casqa.org 2 of 2 PA2017-045 Paving and Grinding Operations NS-3 "" Description and Purpose Prevent or reduce the discharge of pollutants from paving operations, using measures to prevent runon and runoff pollution, properly disposing of wastes, and training employees and subcontractors. The General Permit incorporates Numeric Action Levels (NAL) for pH and turbidity (see Section 2 of this handbook to determine your project's risk level and if you are subject to these requirements). Many types of construction materials associated with paving and grinding operations, including morta.r, concrete, and cement and their associated wastes have basic chemical properties that can raise pH levels outside of the permitted range. Additional care should be taken when managing these materials to prevent them from coming into contact with stormwater flows, which could lead to exceedances of the General Permit requirements. Suitable Applications These procedures are implemented where paving, surfacing, resurfacing, or sawcutting, may pollute stormwater runoff or discharge to the storm drain system or watercourses. Limitations • Paving opportunities may be limited during wet weather. Discharges of freshly paved surfaces may raise pH to environmentally harmful levels and trigger permit violations.

CALlfORNIA STO!lMWATill l.}l'/\LIT'r .-i.~~Ul 1,\1 IO:--.; 1 of 5 PA2017-045 Paving and Grinding Operations Implementation General • Avoid paving during the wet season when feasible. 11 Reschedule paving and grinding activities if rain is forecasted. • Train employees and sub-contractors in pollution prevention and reduction. NS-3 • Store materials away from drainage courses to prevent stormwater runon (see WM-1, Material Delivery and Storage). 11 Protect drainage courses, particularly in areas with a grade, by employing BMPs to divert runoff or to trap and filter sediment. • Stockpile material removed from roadways away from drain inlets, drainage ditches, and watercourses. These materials should be stored consistent with WM-3, Stockpile Management. m Disposal of PCC (Portland cement concrete) and AC (asphalt concrete) waste should be in conformance with WM-8, Concrete Waste Management. Saw Cutting, Grinding, and Pavement Removal • Shovel or vacuum saw-cut slurry and remove from site~ Cover or barricade storm drains during saw cutting to contain slurry. • When paving involves AC, the following steps should be implemented to prevent the discharge of grinding residue, uncompacted or loose AC, tack coats, equipment cleaners, or unrelated paving materials: AC grindings, pieces, or chunks used in embankments or shoulder backing should not be allowed to enter any storm drains or watercourses. Install inlet protection and perimeter cuntrols until area is stabilized (i.e. cutting, grinding or other removal activities are complete and loose material has been properly removed and disposed oDor permanent controls are in place. Examples of temporary perimeter controls can be found in EC-9, Earth Dikes and Drainage Swales; SE-1, Silt Fence; SE-5, Fiber Rolls, or SE-13 Compost Socks and Berms Collect and remove all broken asphalt and recycle when practical. Old or spilled asphalt should be recycled or disposed of properly. • Do not allow saw-cut slurry to enter storm drains or watercourses. Residue from grinding operations should be picked up by a vacuum attachment to the grinding machine, or by sweeping, should not be allowed to flow across the pavement, and should not be left on the surface of the pavement. See also WM-8, Concrete Waste Management, and WM-10, Liquid Waste Management. • Pavement removal activities should not be conducted in the rain. • Collect removed pavement material by mechanical or manual methods. This material may be recycled for use as shoulder backing or base material. July 2012 California Stormwater BMP Handbook Construction www.casqa.org 2 of 5 PA2017-045 Paving and Grinding Operations NS-3 11 If removed pavement material cannot be recycled, transport the material back to an approved storage site. Asphaltic Concrete Paving • If paving involves asphaltic cement concrete, follow these steps: Do not allow sand or gravel placed over new asphalt to wash into storm drains, streets, or creeks. Vacuum or sweep loose sand and gravel and properly dispose of this waste by referring to WM-5, Solid Waste Management. Old asphalt should be disposed of properly. Collect and remove all broken asphalt from the site and recycle whenever possible. Portland Cement Concrete Paving • Do not wash sweepings from exposed aggregate concrete into a storm drain system. Collect waste materials by dry methods, such as sweeping or shoveling, and return to aggregate base stockpile or dispose of properly. Allow aggregate rinse to settle. Then, either allow rinse water to dry in a temporary pit as described in WM-8, Concrete Waste Management, or pump the water to the sanitary sewer if authorized by the local wastewater authority. Sealing Operations • During chip seal application and sweeping operations, petroleum or petroleum covered aggregate should not be allowed to enter any storm drain or water courses. Apply temporary perimeter controls until structure is stabilized (i.e. all sealing operations are complete and cured and loose materials have been properly removed and disposed). • Inlet protection (SE-10, Storm Drain Inlet Protection) should be used during application of seal coat, tack coat, slurry seal, and fog seal. • Seal coat, tack coat, slurry seal, or fog seal should not be applied if rainfall is predicted to occur during the application or curing period. Paving Equipment • Leaks and spills from paving equipment can contain toxic levels of heavy metals and oil and grease. Place drip pans or absorbent materials under paving equipment when not in use. Clean up spills with absorbent materials and dispose of in accordance with the applicable regulations. See NS-10, Vehicle and Equipment Maintenance, WM-4, Spill Prevention and Control, and WM-10, Liquid Waste Management. • Substances used to coat asphalt transport trucks and asphalt spreading equipment should not contain soap and should be non-foaming and non-toxic. • Paving equipment parked onsite should be parked over plastic to prevent soil contamination. • Clean asphalt coated equipment offsite whenever possible. When cleaning dry, hardened asphalt from equipment, manage hardened asphalt debris as described in WM-5, Solid Waste Management. Any cleaning onsite should follow NS-8, Vehicle and Equipment Cleaning. July 2012 California Stormwater BMP Handbook Construction www .casqa.org 3 of 5 PA2017-045 Paving and Grinding Operations NS-3 Thermoplastic Striping 11 Thermoplastic striper and pre-heater equipment shutoff valves should be inspected to ensure that they are working properly to prevent leaking thermoplastic from entering drain inlets, the storrnwater drainage system, or watercourses. • Pre-heaters should be filled carefully to prevent splashing or spilling of hot thermoplastic. Leave six inches of space at the top of the pre-heater container when filling thermoplastic to allow room for material to move. • Do not pre-heat, transfer, or load thermoplastic near drain inlets or watercourses. • Clean truck beds daily ofloose debris and melted thermoplastic. When possible, recycle thermoplastic material. Raised/Recessed Pavement Marker Application and Removal • Do not transfer or load bituminous material near drain inlets, the stormwater drainage system, or watercourses. • Melting tanks should be loaded with cate and not filled to beyond six inches from the top to leave room for splashing. • When servicing or filling melting tanks, ensure all pressure is released before removing lids to avoid spills. • On large-scale projects, use mechanical or manual methods to collect excess bituminous material from the roadway after removal of markers. Costs • All of the above are low cost measures. Inspection and Maintenance • Inspect and vsrify that activity-based I3MPs are in place prior to the commencement of paving and grinding operations. • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Sample stormwater runoff required by the General Permit. • Keep ample supplies of drip pans or absorbent materials onsite. • Inspect and maintain machinery regularly to minimize leaks and drips.

Concrete curing includes the use of both chemical and water methods. Concrete and its associated curing materials have basic chemical properties that can raise the pH of water to levels outside of the permitted range. Discharges of storm water and non-stormwater exposed to concrete during curing may have a high pH and may contain chemicals, metals, and fines. The General Permit incorporates Numeric Action Levels (NAL) for pH (see Se~ction 2 of this handbook to determine your project's risk level and if you are subject to these requirements). Proper procedures and care should betaken when managing concrete curing materials to prevent them from coming into contact with stormwater flows, which could result in a high pH discharge. Suitable Applications Suitable applications include all projects where Portland Cement Concrete (PCC) and concrete curing chemicals are placed where they can be exposed to rainfall, runoff from other areas, or where runoff from the PCC will leave the site. Limitations • Runoff contact with concrete waste can raise pH levels in the water to environmentally harmful levels and trigger permit violations.

Implementation The following steps should be taken to minimize risk: • Chemicals must be stored in water tight containers with appropriate secondary containment or in a storage shed. • When a material storage area is located on bare soil, the area should be lined and bermed. • Use containment pallets or other practical and available solutions, such as storing materials within newly constructed buildings or garages, to meet material storage requirements. • Stack erodible landscape material on pallets and cover when not in use. • Contain all fertilizers and other landscape materials when not in use. • Temporary storage areas should be located away from vehicular traffic. • Material Safety Data Sheets (MSDS) should be available on-site for all materials stored that have the potential to effect water quality. • Construction site areas should be designated for material delivery and storage. • Material delivecy and storage areas should be located away from waterways, if possible. Avoid transport near drainage paths or waterways. Surround with earth berms or other appropriate containment BMP. See EC-9, Earth Dike.sand Drainage Swales. Place in an area that will be paved. • Storage of reactive, ignitable, or flammable liquids must comply with the fire codes of your area. Contact the local Fire Marshal to review site materials, quantities, and proposed storage area to determine specific requirements. See the Flammable and Combustible Liquid Code, NFP A.30. • An up to date inventory of materials delivered and stored onsite should be kept. November 2009 California Stormwater BMP Handbook Construction www.casqa.org 2 of 5 PA2017-045 Material Delivery and Storage WM-1 • Hazardous materials storage onsite should be minimized. • Hazardous materials should be handled as infrequently as possible. • Keep ample spill cleanup supplies appropriate for the materials being stored. Ensure that cleanup supplies are in a conspicuous, labeled area. • Employees and subcontractors should be trained on the proper material delivery and storage practices. • Employees trained in emergency spill cleanup procedures must be present when dangerous materials or liquid chemicals are unloaded. 11 If significant residual materials remain on the ground after construction is complete, properly remove and dispose of materials and any contaminated soil. See WM-7, Contaminated Soil Management. If the area is to be paved, pave as soon as materials are removed to stabilize the soil. Material Storage Areas and Practices • Liquids, petroleum products, and substances listed in 40 CFR Parts 110, 117, or 302 should be stored in approved containers and drums and should not be overfilled. Containers and drums should be placed in temporary containment facilities for storage. • A temporary containment facility should provide for a spill containment volume able to contain precipitation from a 25 year storm event, plus the greater of 10% of the aggregate volume of all containers or 100% of the capacity of the largest container within its boundary, whichever is greater. • A temporary containment facility should be impervious to the materials stored therein for a minimum contact time of 72 hours. • A temporary containment facility should be maintained free of accumulated rainwater and spills. in the event of spills or teaks, accumulated rainwater and spills should be collected and placed into drums. These liquids should be handled as a hazardous waste unless testing determines them to be non-hazardous. All collected liquids or non-hazardous liquids should be sent to an approved disposal site. • Sufficient separation should be provided between stored containers to allow for spill cleanup and emergency response access. • Incompatible materials, such as chlorine and ammonia, should not be stored in the same temporary containment facility. • Materials should be covered prior to, and during rain events. • Materials should be stored in their original containers and the original product labels should be maintained in place in a legible condition. Damaged or otherwise illegible labels should be replaced immediately. November 2009 California Stormwater BMP Handbook Construction www.casqa.org 3 of S PA2017-045 Material Delivery and Storage WM-1 • Bagged and boxed materials should be stored on pallets and should not be allowed to accumulate on the ground. To provide protection from wind and rain throughout the rainy season, bagged and boxed materials should be covered during non-working days and prior to and during rain events. • Stockpiles should be protected in accordance with WM-3, Stockpile Management. • Materials should be stored indoors within existing structures or completely enclosed storage sheds when available. a Proper storage instructions should be posted at all times in an open and conspicuous location. • An ample supply of appropriate spill clean up material should be kept near storage areas. • Also see WM-6, Hazardous Waste Management, for storing of hazardous wastes. Material Delivery Practices • Keep an accurate, up-to-date inventory of material delivered and stored onsite. • Arrange for employees trained in emergency spill cleanup procedures to be present when dangerous materials or liquid chemicals are unloaded. Spill Cleanup • Contain and clean up any spill immediately. • Properly remove and dispose of any hazardous materials or contaminated soil if significant residual materials remain on the ground after construction is complete. See WM-7, Contaminated Soil Management. • See WM-4, Spill Prevention and Control, for spills of chemicals and/or hazardous materials. • ~ If spills or leaks of materials occur that are not contained and could discharge to surface waters, non-visible sampling of site discharge may be required. Refer to the General Permit or to your project specific Construction Site Monitoring Plan to determine if and where sampling is required. Cost • The largest cost of implementation may be in the construction of a materials storage area that is covered and provides secondary containment. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Keep storage areas clean and well organized, including a current list of all materials onsite. • Inspect labels on containers for legibility and accuracy.

All stockpiles are required to be protected as non-active stockpiles immediately if they are not scheduled to be used within 14 days. • Protect all stockpiles from stormwater runon using temporary perimeter sediment barriers such as compost berms (SE-13), temporary silt dikes (SE-12), fiber rolls (SE-5), silt fences (SE-1), sandbags (SE-8), gravel bags (SE-6), or biofilter bags (SE-14). Refer to the individual fact sheet for each of these controls for installation information. • Implement wind erosion control practices as appropriate on all stockpiled material. For specific information, see WE-1, Wind Erosion Control. • Manage stockpiles of contaminated soil in accordance with WM-7, Contaminated Soil Management. • Place bagged materials on pallets and under cover. • Ensure that stockpile coverings are installed securely to protect from wind and rain. • Some plastic covers withstand weather and sunlight better than others. Select cover materials or methods based on anticipated duration of use. Protection of Non-Active Stockpiles A stockpile is considered non-active if it either is not used for 14 days or if it is scheduled not to be used for 14 days or more. Stockpiles need to be protected immediately if they are not scheduled to be used within 14 days. Non-active stockpiles of the identified materials should be protected as follows: Soil stockpiles • Soil ;tock.piles should be cov~red or protected with sa"il stabilization measure; and a temporary perimeter sediment barrier at all times. • Temporary vegetation should be considered for topsoil piles that will be stockpiled for extended periods. Stockpiles of Portland cement concrete rubble, asphalt concrete, asphalt concrete rubble, aggregate base, or aggregate sub base • Stockpiles should be covered and protected with a temporary perimeter sediment barrier at all times. Stockpiles of"cold mix" • Cold mix stockpiles should be placed on and covered with plastic sheeting or comparable material at all times and surrounded by a berm. Stockpiles of fly ash, stucco, hydrated lime July 2012 California Stormwater BMP Handbook Construction www.casqa.org 2 of 3 PA2017-045 Stockpile Management ·WM--3 • Stockpiles of materials that may raise the pH of runoff (i.e., basic materials) should be covered with plastic and surrounded by a berm. Stockpiles/Storage of wood (Pressure treated with chromated copper arsenate or ammonia cal copper zinc arsenate • Treated wood should be covered with plastic sheeting or comparable material at all times and surrounded by a berm. Protection of Active Stockpiles A stockpile is active when it is being used or is scheduled to be used within 14 days of the previous use. Active stockpiles of the identified materials should be protected as follows: • All stockpiles should be covered and protected with a temporary linear sediment barrier prior to the onset of precipitation. • Stockpiles of "cold mix" and treated wood, and basic materials should be placed on and covered with plastic sheeting or comparable material and surrounded by a berm prior to the onset of precipitation. • The downstream perimeter of art active stockpile should be protected with a linear sediment barrier or berm and runoff should be diverted around or away from the stockpile on the upstream perimeter. Costs For cost information associated with stockpile protection refer to the individual erosion or sediment control BMP fact sheet considered for implementation (For example, refer to SE-1 Silt Fence for installation of silt fence around the perimeter of a stockpile.) Inspection and Maintenance • Stockpiles must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be 0 inspected weekly, prior to forecasted rain eveftts, daily during extende'd rain events, and after the conclusion of rain events. • It may be necessary to inspect stockpiles covered with plastic sheeting more frequently during certain conditions (for example, high winds or extreme heat). • Repair and/or replace perimeter controls and covers as needed to keep them functioning properly. • Sediment shall be removed when it reaches one-third of the barrier height.

Contractor should identify appropriate practices for the specific materials used or stored onsite Implementation The following steps will help reduce the stormwater impacts of leaks and spills: Education • Be aware that different materials pollute in different amounts. Make sure that each employee knows what a "significant spill" is for each material they use, and what is the appropriate response for "significant" and "insignificant" spills. • Educate employees and subcontractors on potential dangers to humans and the environment from spills and leaks. • Hold regular meetings to discuss and reinforce appropriate disposal procedures (incorporate into regular safety meetings). • Establish a continuing education program to indoctrinate new employees. • Have contractor's superintendent or representative oversee and enforce proper spill prevention ap.d control measures. General}lfeasures • To the extent that the work can be accomplished safely, spills of oil, petroleum products, substances listed under 40 CFR parts 110,117, and 302, and sanitary and septic wastes should be contained and cleaned up immediately. • Store hazardous materials and wastes in covered containers and protect from vandalism. • Place a stockpile of spill cleanup materials where it will be readily accessible. • Train employees in spill prevention and cleanup. • Designate responsible individuals to oversee and enforce control measures. • Spills should be covered and protected from stormwater runon during rainfall to the extent that it doesn't compromise clean up activities. • Do not bury or wash spills with water. January 2011 Californra Stormwater BMP Handbook·· Construct"1on www.casqa.org 2 of 6 PA2017-045 Spill Prevention and C:ontrol WM-4 • Store and dispose of used clean up materials, contaminated materials, and recovered spill material that is no longer suitable for the intended purpose in conformance with the provisions in applicable BMPs. • Do not allow water used for cleaning and decontamination to enter storm drains or watercourses. Collect and dispose of contaminated water in accordance with WM-10, Liquid Waste Management. • Contain water overflow or minor water spillage and do not allow it to discharge into drainage facilities or watercourses. • Place proper storage, cleanup, and spill reporting instructions for hazardous materials stored or used on the project site in an open, conspicuous, and accessible location. • Keep waste storage areas clean, well organized, and equipped with ample cleanup supplies as appropriate for the materials being stored. Perimeter controls, containment structures, covers, and liners should be repaired or replaced as needed to maintain proper function. Cleanup 11 Clean up leaks and spills immediately. • Use a rag for small spills on paved surfaces, a damp mop for general cleanup, and absorbent material for larger spills. If the spilled material is hazardous, then the used cleanup materials are also hazardous and must be sent to either a certified laundry (rags) or disposed of as hazardous waste. • Never hose down or bury dry material spills. Clean up as much of the material as possible and dispose ofproperly. See the waste management BMPs in this section for specific information. Minor Spills • Minor spills typically involve.small quantities of oil, gasoline, paint, etc. which can be controlled by the first responder at the discovery of the spill. • Use absorbent materials on small spills rather than hosing down or burying the spill. • Absorbent materials should be promptly removed and disposed of properly. • Follow the practice below for a minor spill: Contain the spread of the spill. Recover spilled materials. Clean the contaminated area and properly dispose of contaminated materials. Semi-Signtfi.cant Spills • Semi-significant spills still can be controlled by the first responder along with the aid of other personnel such as laborers and the foreman, etc. This response may require the cessation of all other activities. January 2011 California Stormwater BMP Handbook Construction www ,casqa ,org 3 of 6 PA2017-045 Spill Prevention and Control WM-4 • Spills should be cleaned up immediately: Contain spread of the spill. Notify the project foreman immediately. If the spill occurs on paved or impermeable surfaces, clean up using "dry" methods (absorbent materials, cat litter and/or rags). Contain the spill by encircling with absorbent materials and do not let the spill spread widely. If the spill occurs in dirt areas, immediately contain the spill by constructing an earthen dike. Dig up and properly dispose of contaminated soil. If the spill occurs during rain, cover spill with tarps or other material to prevent contaminating runoff. Significant/Hazardous Spills • For significant or hazardous spills that cannot be controlled by personnel in the immediate vicinity, the following steps should be taken: Notify the local emergency response by dialing 911. In addition to 911, the contractor Vvill notify the proper county officials. It is the contractor's responsibility to have all emergency phone numbers at the construction site. Notify the Governor's Office of Emergency Services Warning Center, (916) 845-8911. For spills of federal reportable quantities, in conformance with the requirements in 40 CFR parts 110,119, and 302, the contractor should notify the National Response Center at (Boo) 424-8802. Notification should first be made by telephone and followed up with a written report. The services of a spills contractor or a Haz-Mat team should be obtained immediately. Construction personnel should not attempt to clean up until the appropriate and qualified staffs have arrived at the job site. Other agencies which may need to be consulted include, but are not limited to, the Fire Department, the Public Works Department, the Coast Guard, the Highway Patrol, the City/County Police Department, Department of Toxic Substances, California Division of Oil and Gas, Cal/OSHA, etc. Reporting • Report significant spills to local agencies, such as the Fire Department; they can assist in cleanup. • Federal regulations require that any significant oil spill into a water body or onto an adjoining shoreline be reported to the National Response Center (NRC) at 800-424-8802 (24 hours). Use the following measures related to specific activities: January 2011 California Storrnwater BMP Handbook .. Construction www.casqa.org 4 of 6 PA2017-045 Spill Prevention and Control. WM-4 Vehicle and Equipment Maintenance • If maintenance must occur onsite, use a designated area and a secondary containment, located away from drainage courses, to prevent the runon of stormwater and the runoff of spills. • Regularly inspect onsite vehicles and equipment for leaks and repair immediately • Check incoming vehicles and equipment (including delivery trucks, and employee and subcontractor vehicles) for leaking oil and fluids. Do not allow leaking vehicles or equipment onsite. • Always use secondary containment, such as a drain pan or drop cloth, to catch spills or leaks when removing or changing fluids. • Place drip pans or absorbent materials under paving equipment when not in use. • Use absorbent materials on small spills rather than hosing down or burying the spill. Remove the absorbent materials promptly and dispose of properly. 111 Promptly transfer used fluids to the proper waste or recycling drums. Don't leave full drip pans or other open containers lying around • Oil filters disposed of in trashcans or dumpsters can leak oil and pollute stormwater. Place the oil filter in a funnel over a waste oil-recycling drum to drain excess oil before disposal. Oil filters can also be recycled. Ask the oil supplier or recycler about recycling oil filters. • Store cracked batteries in a non-leaking secondary container. Do this with all cracked batteries even if you think all the acid has drained out. If you drop a battery, treat it as if it is cracked. Put it into the containment area until you are sure it is not leaking. Vehicle and Equipment Fueling • If fueling mu~t occur onsite, use designate areas, located away from drainage courses,. to prevent the runon of stormwater and the runoff of spills. • Discourage "topping off' of fuel tanks. • Always use secondary containment, such as a drain pan, when fueling to catch spills/ leaks. Costs Prevention of leaks and spills is inexpensive. Treatment and/ or disposal of contaminated soil or water can be quite expensive. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect BMPs in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. January 2011 Californla Stormwater BMP Handbook Construction www.casqa.org 5 of 6 PA2017-045 Spill Prevention and Control WM-4 • Inspect BMPs subject to non-stormwater discharge daily while non-stormwater discharges occur. • Keep ample supplies of spill control and cleanup materials onsite, near storage, unloading, and maintenance areas. • Update your spill prevention and control plan and stock cleanup materials as changes occur in the types of chemicals onsite.

Implementation The following steps will help keep a clean site and reduce stormwater pollution: • Select designated waste collection areas onsite. • Inform trash-hauling contractors that you will accept only watertight dumpsters for onsite use. Inspect dumpsters for leaks and repair any dumpster that is not watertight. • Locate containers in a covered area or in a secondary containment. • Provide an adequate number of containers with lids or covers that can be placed over the container to keep rain out or to prevent loss of wastes when it is windy. • Cover waste containers at the end of each work day and when it is raining. • Plan for additional containers and more frequent pickup during the demolition phase of construction. • Collect site trash daily, especially during rainy and windy conditions. • Remove this solid waste promptly since erosion and sediment control devices tend to co11ect litter. • Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids, pesticides, additives, curing compounds) are not disposed of in dumpsters designated for 0 construction debris. 0 0 0 • Do not hose out dumpsters on the construction site. Leave dumpster cleaning to the trash hauling contractor. • Arrange for regular waste collection before containers overflow. • Clean up immediately if a container does spill. • Make sure that construction waste is collected, removed, and disposed of only at authorized disposal areas. Education • Have the contractor's superintendent or representative oversee and enforce proper solid waste management procedures and practices. • Instruct employees and subcontractors on identification of solid waste and hazardous waste. • Educate employees and subcontractors on solid waste storage and disposal procedures. January 2011 California Stormwater BMP Handbook Construction www.casqa.org 2 of 4 PA2017-045 Solid Waste Management WM-5 • Hold regular meetings to discuss and reinforce disposal procedures (incorporate into regular safety meetings). • Require that employees and subcontractors follow solid waste handling and storage procedures. • Prohibit littering by employees, subcontractors, and visitors. • Minimize production of solid waste materials wherever possible. Collection, Storage, and Disposal • Littering on the project site should be prohibited. • To prevent clogging of the storm drainage system, litter and debris removal from drainage grates, trash racks, and ditch lines should be a priority, • Trash receptacles should be provided in the contractor's yard, field trailer areas, and at locations where workers congregate for lunch and break periods. • Litter from work areas ·within the construction limits of the project site should be collected and placed in watertight dumpsters at least weekly, regardless of whether the litter was generated by the contractor, the public, or others. Collected litter and debris should not be placed in or next to drain inlets, stormwater drainage systems, or watercourses. • Dumpsters of sufficient size and number should be provided to contain the solid waste generated by the project. • Full dumpsters should be removed from the project site and the contents should be disposed of by the trash hauling contractor. • Construction debris and waste should be removed from the site biweekly or more frequently as needed. • Construction material visible to the public should be stored or stacked in an orderly manner. • Stormwater runon should be prevented from contacting stored solid waste through the use of berms, dikes, or other temporary diversion structures or through the use of measures to elevate waste from site surfaces. • Solid waste storage areas should be located at least 50 ft from drainage facilities and watercourses and should not be located in areas prone to flooding or ponding. • Except during fair weather, construction and highway planting waste not stored in watertight dumpsters should be securely covered from wind and rain by covering the waste with tarps or plastic. • Segregate potentially hazardous waste from non~hazardous construction site waste. • Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids, pesticides, additives, curing compounds) are not disposed of in dumpsters designated for construction debris. January 2011 California Stormwater BMP Handbook Construction www.casqa.org 3 of 4 PA2017-045 Solid Waste Management WM-5 • For disposal of hazardous waste, see WM-6, Hazardous Waste Management. Have hazardous waste hauled to an appropriate disposal and/or recycling facility. • Salvage or recycle useful vegetation debris, packaging and surplus building materials when practical. For example, trees and shrubs from land clearing can be used as a brush barrier, or converted into wood chips, then used as mulch on graded areas. Wood pallets, cardboard boxes, and construction scraps can also be recycled. Costs All of the above are low cost measures. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities.

The General Permit incorporates Numeric Action Levels (NAL) for pH (see Section 2 of this handbook to determine your project's risk level and if you are subject to these requirements). Many types of construction materials, including: mortar, concrete, stucco, cement and block and their associated wastes have basic chemical properties that call raise pH levels outside of the permitted range. Additional care should be taken when managing these materials to pre;ent them from coming into contact with storm water flows and raising pH to levels outside the accepted range. Suitable Applications Concrete waste management procedures and practices are implemented on construction projects where: • Concrete is used as a construction material or where concrete dust and debris result from demolition activities. • Slurries containing portland cement concrete (PCC) are generated, such as from saw cutting, coring, grinding, grooving, and hydro-concrete demolition. • Concrete trucks and other concrete-coated equipment are washed onsite.

Limitations • Offsite washout of concrete wastes may not always be possible. • Multiple washouts may be needed to assure adequate capacity and to allow for evaporation. Implementation The following steps will help reduce stormwater pollution from concrete wastes: • Incorporate requirements for concrete waste management into material supplier and subcontractor agreements. • Store dry and wet materials under cover, away from drainage areas. Refer to WM-1, Material Delivery and Storage for more information. 11 Avoid mixing excess amounts of concrete. • Perform washout of concrete trucks in designated areas only, where washout will not reach stormwater. • Do not wash out concrete trucks into storm drains, open ditches, streets, streams or onto the ground. Trucks should always be washed out into designated facilities. • Do not allow excess concrete to be dumped onsite, except in designated areas. • For onsite washout: On larger sites, it4s recommended to locate washout areas at least .. 50 feet from storm drains, open ditches, or water bodies. Do not allow runoff from this area by constructing a temporary pit or bermed area large enough for liquid and solid waste. Washout wastes into the temporary washout where the concrete can set, be broken up, and then disposed properly. Washouts shall be implemented in a manner that prevents leaching to unclerlying soils. Washout containers must be water tight and washouts on or in the ground must be lined with a suitable impervious liner, typically a plastic type material. • Do not wash sweepings from exposed aggregate concrete into the street or storm drain. Collect and return sweepings to aggregate base stockpile or dispose in the trash. • See typical concrete washout installation details at the end of this fact sheet. Education • Educate employees, subcontractors, and suppliers on the concrete waste management techniques described herein. July 2012 California Stormwater BMP Handbook Construction www.casqa.org 2 of 7 PA2017-045 Concrete Waste Management WM-8 • Arrange for contractor's superintendent or representative to oversee and enforce concrete waste management procedures. • Discuss the concrete management techniques described in this BMP (such as handling of concrete waste and washout) with the ready-mix concrete supplier before any deliveries are made. Concrete Demolition Wastes • Stockpile concrete demolition waste in accordance with BMP WM-3, Stockpile Management. 11 Dispose of or recycle hardened concrete waste in accordance with applicable federal, state or local regulations. Concrete Slurry Wastes • PCC and AC waste should not be allowed to enter storm drains or watercourses. • PCC and AC waste should be collected and disposed of or placed in a temporary concrete washout facility (as described in Onsite Temporary Concrete Washout Facility, Concrete Transit Truck Washout Procedures, below). • A foreman or construction supervisor should monitor onsite concrete working tasks, such as saw cutting, coring, grinding and grooving to ensure proper methods are implemented. 11 Saw-cut concrete slurry should not be allowed to enter storm drains or watercourses. Residue from grinding operations should be picked up by means of a vacuum attachment to the grinding machine or by sweeping. Saw cutting residue should not be allowed to flow across the pavement and should not be left on the surface of the pavement. See also NS-3, Paving and Grinding Operations; and WM-10, Liquid Waste Management. • Concrete slurry residue should be disposed in a temporary washout facility (as described in Onsite Temporary Concrete Washout Facility, Concrete Transit Truck Washout Procedures, below) and allowed to dry. Dispose of dry slurry residue in accordance with WM-5, SoJid Waste Management. Onsite Temporary Concrete Washout Facility, Transit Truck Washout Procedures • Temporary concrete washout facilities should be located a minimum of 50 ft from storm drain inlets, open drainage facilities, and watercourses. Each facility should be located away from construction traffic or access areas to prevent disturbance or tracking. • A sign should be installed adjacent to each washout facility to inform concrete equipment operators to utilize the proper facilities. • Temporary concrete washout facilities should be constructed above grade or below grade at the option of the contractor. Temporary concrete washout facilities should be constructed and maintained in sufficient quantity and size to contain all liquid and concrete waste generated by washout operations. July 2012 California Stormwater BMP Handbook Construction www.casqa.org 3 of 7 PA2017-045 Concrete Waste Management WM-8 • Temporary washout facilities should have a temporary pit or bermed areas of sufficient volume to completely contain all liquid and waste concrete materials generated during washout procedures. • Temporary washout facilities should be lined to prevent discharge to the underlying ground or surrounding area. • Washout of concrete trucks should be performed in designated areas only. • Only concrete from mixer truck chutes should be washed into concrete wash out. • Concrete washout from concrete pumper bins can be washed into concrete pumper trucks and discharged into designated washout area or properly disposed of or recycled offsite. • Once concrete wastes are washed into the designated area and allowed to harden, the concrete should be broken up, removed, and disposed of per WM-5, Solid Waste Management. Dispose of or recycle hardened concrete on a regular basis. • Temporary Concrete Washout Facility (Type Above Grade) Temporary concrete washout facility (type above grade) should be constructed as shown on the details at the end of this BMP, with a recommended minimum length and minimum width of 10 ft; however, smaller sites or jobs may only need a smaller washout facility. With any washout, always maintain a sufficient quantity and volume to contain all liquid and concrete waste generated by washout operations. Materials used to construct the washout area should conform to the provisions detailed in their respective BMPs (e.g., SE~8 Sandbag Barrier). Plastic lining material should be a minimum of 10 mil in polyethylene sheeting and should be free of holes, tears, or other defects that compromise the impermeability of the material. Alternatively, portable removable containers can be used as above grade concrete washouts. Also called a "roll-off'; this concrete washout facility should be properly sealed to prevent leakage, and should be removed from the site and replaced when the container reaches 75% capacity. • Temporary Concrete Washout Facility (Type Below Grade) Temporary concrete washout facilities (type below grade) should be constructed as shown on the details at the end of this BMP, with a recommended minimum length and minimum width of 10 ft. The quantity and volume should be sufficient to contain all liquid and concrete waste generated by washout operations. Lath and flagging should be commercial type. Plastic lining material should be a minimum of 10 mil polyethylene sheeting and should be free of holes, tears, or other defects that compromise the impermeability of the material. July 2012 California Stormwater BMP Handbook · Construction www.casqa.org 4 of 7 PA2017-045 Concrete Waste Management WM-8 The base of a washout facility should be free of rock or debris that may damage a plastic liner. Removal ofTemporary Concrete Washout Facilities • When temporary concrete washout facilities are no longer required for the work, the hardened concrete should be removed and properly disposed or recycled in accordance with federal, state or local regulations. Materials used to construct temporary concrete washout facilities should be removed from the site of the work and properly disposed or recycled in accordance with federal, state or local regulations .. • Holes, depressions or other ground disturbance caused by the removal of the temporary concrete washout facilities should be backfilled and repaired. Costs All of the above are low cost measures. Roll-off concrete washout facilities can be more costly than other measures due to removal and replacement; however, provide a cleaner alternative to traditional washouts. The type of washout facility, size, and availability of materials will determine the cost of the washout. Inspection and Maintenance 11 BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Temporary concrete washout facilities should be maintained to provide adequate holding capacity with a minimum freeboard of 4 in. for above grade facilities and 12 in. for below grade facilities. Maintaining temporary concrete washout facilities should include removing and disposing of hardened concrete and returning the facilities to a functional condition. Hardened concrete materials should be removed and properly disposed or recycled in accordance with federal, state or local regulations. ~ ~ • Washout facilities must be cleaned, or new facilities must be constructed and ready for use once the washout is 75% full. • Inspect washout facilities for damage (e.g. torn liner, evidence ofleaks, signage, etc.). Repair all identified damage.

Management WM-9 Description and Purpose Proper sanitary and septic waste management prevent the discharge of pollutants to storm water from sanitary and septic waste by providing convenient, well-maintained facilities, and arranging for regular service and disposal. Suitable Applications Sanitary septic waste management practices are suitable for use at all construction sites that use temporary or portable sanitary and septic waste systems. Limitations None identified. Implementation Sanitary or septic wastes should be treated or disposed of in accordance with state and local requirements. In many cases, one contract with a local facility supplier will be all that it takes to make sure sanitary wastes are properly disposed. Storage and Disposal Procedures • Temporary sanitary facilities should be located away from drainage facilities, watercourses, and from traffic circulation. If site conditions allow, place portable facilities a minimum of 50 feet from drainage conveyances and traffic areas. When subjected to high winds or risk of high winds, temporary sanitary facilities should be secured to prevent overturning.

Equcation • Educate employees, subcontractors, and suppliers on sanitary and septic waste storage and disposal procedures. • Educate employees, subcontractors, and suppliers of potential dangers to humans and the environment from sanitary and septic wastes. • Instruct employees, subcontractors, and suppliers in identification of sanitary and septic waste. • Hold regular meetings to discuss and reinforce the use of sanitary facilities (incorporate into regular safety meetings). • Establish a continuing education program to indoctrinate new employees. Costs All of the above are low cost measures. November 2009 California Stormwater BMP Handbook Construction www .casqa.org 2 of 3 PA2017-045 Sanitary/Sep~ic WastE!Manageanent WM-9 Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion cif rain events. • Arrange for regular waste collection. • If high winds are expected, portable sanitary facilities must be secured with spikes or weighed down to prevent over turning. • If spills or lea.ks from sanitary or septic facilities occur that are not contained and discharge from the site, non-visible sampling of site discharge may be required. Refer to the General Permit or to your project specific Construction Site Monitoring Plan to determine ifand where sampling is required.

Printed Name: ------------------------------------- Signature:---------------------------Dat~e~: ________ _ Title:-------------------------------------- -7- PA2017-045 2014-2015 ANNUAL REPORT DESCRIPTION OF BASIC ANALYTICAL PARAMETERS The Industrial Activities Storm Water General Permit (General Permit) requires you to analyze storm water samples for at least four parameters. These are pH, Total Suspended Solids (TSS), Specific Conductance (SC),and Total Organic Carbon (TOG). Oil and Grease (O&G) may be substituted for TOG. In addition, you must monitor for any other pollutants which you believe to be present in your storm water discharge as a result of industrial activity and analytical parameters listed in Table D of the General Permit. There are no numeric limitations for the parameters you test for. The four parameters which the General Penn it requires to be tested are considered indicator parameters. In other words, regardless of what type of facility you operate, these parameters are nonspecific and general enough to usually provide some indication whether pollutants are present in your storm water discharge. The following briefly explains what each of these parameters mean: pH is a numeric measure of the hydrogen-ion concentration. The neutral, or acceptable, range is within 6.5 to 8.5. At values less than 6.5, the water is considered acidic; above 8.5 it is considered alkaline or basic. An example of an acidic substance is vinegar, and a alkaline or basic substance is liquid antacid. Pure rainfall tends to have a pH of a little Jess than 7. There may be sources of materials or industrial activities which could increase or decrease the pH of your storm water discharge. If the pH levels of your storm water discharge are high or low, you should conduct a thorough evaluation of all potential pollutant sources at your site. Total Suspended Solids {TSS) is a measure of the undissolved solids that are present in your storm water discharge. Sources of TSS include sediment from erosion of exposed land, and dirt from impervious (i.e. paved) areas. Sediment by itself can be very toxic to aquatic life because it covers feeding and breeding grounds, and can smother organisms living on the bottom of a water body. Toxic chemicals and other pollutants also adhere to sediment particles. This provides a medium by which toxic or other pollutants end up in our water ways and ultimately in human and aquatic life. TSS levels vary in runoff from undisturbed land. It has been shown that TSS levels increase significantly due to land development. Specific Conductance (SC} is a numerical expression of the ability of the water to carry an electric current. SC can be used to assess the degree of mineralization, salinity, or estimate the total dissolved solids concentration of a water sample. Because of air pollution, most rain water has a SC a little above zero. A high SC could affect the usability of waters for drinking, irrigation, and other commercial or industrial use. Total Organic Carbon (TOC) is a measure of the total organic matter present in water. (All organic matter contains carbon) This test is sensitive and able to detect small concentrations of organic matter. Organic matter is naturally occurring in animals, plants, and man. Organic matter may .also be man made (so called synthetic organics). Synthetic organics include pesticides, fuels, solvents, and paints. Natural organic matter utilizes the oxygen in a receiving water to biodegrade. Too much organic matter could place a significant oxygen demand on the water, and possibly impact its quality. Synthetic organics either do not biodegrade or biodegrade very slowly. Synthetic organics are a source of toxic ·chemicals that can have adverse affects at very low concentrations. Some of these chemicals bioaccumufate in aquatic life. If your levels of TOG are high, you should evaluate all sources of natural or synthetic organics you may use at your site. Oil and Grease (O&G) is a measure of the amount of oil and grease present in your storm water discharge. At very low concentrations, O&G can cause a sheen (that floating "rainbow") on the surface of water (1 qt. of oil can pollute 250,000 gallons of water). O&G can adversely affect aquatic life and create unsightly floating material and film on wa.ter, thus making it undrinkable. Sources of O&G include maintenance shops, vehicles, machines and roadways. If you have any questions regarding whether or not your consmuent concentrations are too high, please contact your local Regional Board office. The United States Environmental Protection Agency {USEPA) has published stormwater discharge benchmarks for a number of parameters. These benchmarks may be helpful when evaluating whether additional BMPs are appropriate. These benchmarks can be accessed at our website at http://www.swrcb.ca.gov. It is. contained in the Sampling and Analysis Reduction Certification.
