2 14.1 Motor Pool Vehicle Rinsing SOP No.: 14.1 SOP Name: Motor Pool Vehicle Rinsing CSU s motor pool provides a vehicle rental service to CSU students, faculty and staff. The vehicles include passenger cars, and vans. This SOP describes the allowable and unallowable procedures for rinsing the exteriors of these vehicles at the motor pool facility on a regular basis. The intent of this SOP is to reduce the use of the existing carwash while simultaneously protecting stormwater from pollution. Rinsing of vehicles will result in small amounts of sediment entering the storm sewer system, however, the quantity of sediment leaving the cars in the rinse water will be minimal and represent a low risk of polluting storm water leaving the site. Rental vehicles can be rinsed in the parking lot, and the rinse water allowed to enter the storm sewer inlets. The intent is to quickly remove dust so the vehicle is clean for the next user. However, to protect stormwater from pollution, the rinsing must conform to the following restrictions: 1. No rinsing off magnesium chloride. If vehicles have road dirt, it is winter, and magnesium chloride has likely been used on the roads, then the vehicle must be washed in the car wash. 2. No use of chemicals in rinse water. Only clean hot or cold water may be used. 3. No cleaning of undercarriage or engine. Only light amounts of sediment, not oil, may be in the rinse water entering the storm sewer. 4. No cleaning of very muddy vehicles or vehicles with caked-on dirt. These must be washed in the car wash. 5. No cleaning of construction equipment or grounds equipment. These typically have oil, grease and large amounts of dirt on them when they return to motor pool and should be washed at the vehicle wash stations. Motor Pool Grounds Heavy equipment SOP No A 9/4/08

3 14.2 Painter Building Concrete Apron Rinsing SOP No.: 14.2 SOP Name: Painter Building Concrete Apron Rinsing Bedding and waste materials are stored in closed containers outside the Painter Building s east side on a concrete apron. This SOP describes the allowable and unallowable procedures for rinsing the concrete apron on a regular basis. The intent of this SOP is to maintain a clean and sanitary area while simultaneously minimizing stormwater pollution. The concrete apron area can be rinsed using a hose and the rinse water allowed to access the gutter. The intent is to maintain a clean and sanitary area, however, to protect stormwater from pollution, the rinsing must conform to the following restrictions: 1. The area must be swept with a broom and cleaned in a dry manner to the extent possible prior to rinsing. Swept up materials must be placed in the on-site waste containers. 2. No use of chemicals in rinse water. Only clean hot or cold water may be used. 3. Rinsing shall only be for small amounts of residual materials that cannot be swept up. 4. If residuals are significant and stormwater pollution is likely, please use pressure washer and shop vac or vacuum truck to containerize the wash water; dispose in sanitary sewer. Laboratory Animal Research SOP No A 8/14/09

4 14.3 De-Icing Chemicals SOP No.: 14.3 SOP Name: De-Icing Chemicals CSU uses de-icing chemicals (de-icers) on roads, sidewalks, steps and ramps. De-icers are used to reduce ice formation and provide traction. In certain winter conditions and on steps and ramps, de-icers are necessary for the safe mobility of drivers, cyclists and pedestrians. CSU stores and uses de-icers in bulk for roads, and from hand-held dispensers for steps, ramps and walkways. Granular de-icers are used, no liquid de-icers are stored or used at CSU. This SOP describes methods of de-icer storage and use so that impact to stormwater is minimized. Bulk De-Icer Storage: CSU purchases de-icer in bulk for use on roads. It is a naturally-occurring granular magnesium chloride and powdered rock that is mined and sold for this purpose. As an interim BMP, CSU currently stores the bulk de-icer in an open-top bunker on South Campus. The bunker is equipped with concrete walls and floor, and a curb at the access entrance, to minimize run-off. However, because de-icer is easily dissolved and transported in stormwater and snowmelt, the state-of-the industry BMP for bulk de-icer storage is a covered storage facility to minimize contact with snow and rain and better control run-off. CSU intends to upgrade its de-icer storage from the open top bunker to a covered storage facility. Bulk De-Icer Use: CSU s grounds crews apply the bulk de-icer on paved roads as needed during winter weather conditions after plowing and brooming. Grounds crews are trained to use the de-icer in a way that protects drivers and pedestrians from slipping, but also minimizes potential impacts to stormwater. Key points include: Plow and broom to the extent possible Do not overload the de-icer spreader Sweep the bulk storage apron after loading Try to minimize clumping and uneven application. Hand-Held De-Icers Facilities and other campus personnel use granular de-icers as-needed on steps, ramps and walkways. Periodic training sessions are provided to facilities employees emphasizing the need to use just the right amount of a de-icer without leaving clumps and mounds that cause unnecessary stormwater pollution. In addition, CSU provides de-icer posters to users in an effort to educate campus personnel that de-icers can pollute stormwater. Grounds Building proctors SOP No A 12/15/09

5 14.4 Snow Storage SOP No.: 14.4 SOP Name: Snow Storage CSU plows and brooms on-campus paved roads, parking lots and sidewalks. The act of piling snow can concentrate pollutants such as sediment or de-icers and contribute to stormwater pollution if the piled snow melts rapidly near a waterway or wetland. This SOP describes methods of snow storage so that impact to stormwater is minimized. Procedure: CSU s grounds crews and heavy equipment operators plow and broom paved roads, parking lots and sidewalks during and after snowfall events. Snow cleared from a parking lot and piled at one edge During the majority of snowfall events, snow is piled up at the corners and edges of paved areas to facilitate traffic circulation. After the weather has cleared, and if conditions allow, the piled snow is spread back out onto the paved surface to speed up the melting process and free up the area used for snow storage. During very large snowfall events when piled snow impedes traffic circulation or parking to an unacceptable level, CSU crews load the snow into dump trucks and transport it to Hughes stadium where it is piled on an unpaved surface near the southern portion of the land owned by CSU. At that location, the snow melts, sublimates and infiltrates. The area is a large slightly concave gravel area that precludes runoff to nearby ditches or waterways. Snow removal crews are trained on the following concepts to minimize stormwater pollution from melting snow: When possible, pile snow in a location so that when it melts it will run through a stormwater Best Management Practice or BMP structure (e.g. retention pond, vegetated buffer or swale designed to filter out sediment) If possible, pile snow on unpaved surfaces so it infiltrates when melting Do not pile snow in or immediately adjacent to a waterway, such as Spring Creek If snow piles are excessively dirty, load and haul to the Hughes stadium location Grounds Heavy Equipment SOP No A 12/15/09

6 14.5 Street Maintenance SOP No.: 14.5 SOP Name: Street Maintenance CSU performs limited street maintenance activities on CSU roads and parking lots. Street maintenance and repair activities have the potential to impact stormwater quality Street maintenance activities performed by CSU crews include grading, pothole repairs and painting. This SOP describes measures intended to minimize impact to stormwater during street maintenance activities. General Concepts: When saw cutting, ensure that no slurry enters the storm drain. Let the slurry dry, sweep it up, and properly dispose of the sweepings or vacuum while saw cutting. Do not perform concrete or asphalt paving work during wet conditions whenever possible. Monitor construction equipment for leaks and use drip pans as necessary. Leaking material containers should be properly discarded and replaced. Store materials in containers under cover when not in use and away from any storm drain inlet. Wash out mixers, delivery trucks, or other equipment in a designated concrete washout area only. Locate concrete washout, portable toilets, and material storage away from storm drain inlets. Material stockpiles will not be stored in stormwater flow lines. Temporary sediment control will be used during temporary, short-term placement while work is actively occurring. Sweep or vacuum the roadway as needed, during construction and once construction is complete. Pothole Repair: Load and unload cold patch asphalt at the covered storage area and sweep apron after loading When conducting repairs, do not drop cold patch asphalt in to nearby storm drain inlets When possible, conduct pothole repairs during dry weather to minimize unnecessary transport of asphalt to storm systems Sweep up excess material before leaving the location Painting and Striping: If possible, schedule painting and striping projects during dry weather Use thermoplastic or epoxy markings in place of paint whenever feasible Use car to prevent splashing or spilling of paints or cleaners. Address any spill immediately, and call EHS if spill response assistance is needed. Grounds Heavy Equipment SOP No A 12/15/09

8 14.6 Grounds Outdoor Materials Storage SOP No.: 14.6 SOP Name: Grounds Outdoor Materials Storage CSU s grounds crews maintain CSU grounds including the lawns, landscaped areas and hardscape areas. Raw materials used in ground maintenance activities that are stored outdoors include topsoil and mulch. Waste materials include lawn clippings, prunings, leaves and other organic wastes. Select waste materials, such as chipped woodwastes, etc., are reused on campus landscape areas as mulch. Organic wastes that are not reused on campus are shipped for offsite recycling or disposal. This SOP describes practices associated with outdoor storage of these materials in a way that minimizes stormwater pollution. Procedure: Store topsoil on unpaved areas and provide erosion control in the Topsoil Stockpile form of wattles or silt fence, when erosion and topsoil transport is likely Mulch can be stored in stockpiles or bunkers. If stockpiled, store on unpaved areas and provide erosion control if erosion is likely. If in bunkers, keep mulch piled towards the back of storage bunkers and sweep the front or apron of the bunker to keep mulch from migrating Grounds Mulch Bunker out Do not place topsoil or mulch stockpiles near a waterway Clean up in vicinity of chipper when finished with chipping project Place waste organics in the organics roll-off, grounds bunker or south campus bunker as soon as possible, do not stockpile grass clippings or leaves on paved areas Chipper Grounds Organics Roll-Off SOP No A 12/15/09

9 14.7 Large Outdoor Events SOP No.: 14.7 SOP Name: Large Outdoor Events Large outdoor events take place at several CSU venues within the MS4 boundary, including Hughes Stadium, the Oval, Monfort Quad, Sherwood Forest, and the Lory Student Center West Lawn. In advance of each event, the event coordinator is required to complete a Special Event Request Form which allows to plan the services and cleanup. Procedure: Stormwater pollution is minimized through the following procedures: Trash and recycling receptacles are scheduled for the event, used and picked up promptly after the event Facilities grounds, solid waste and labor crews are notified in advance of each event The event coordinator may be required to contract for portable toilets, at the direction of. The area is cleaned up and inspected by grounds, solid waste or labor crews who notify managers if additional cleanup by outside contractors is necessary. Grounds Labor Crews Integrated Solid Waste SOP No A 2/19/10

10 14.8 Outdoor Fertilizing and Pest Control SOP No.: 14.8 SOP Name: Outdoor CSU grounds crews apply fertilizers and use pest control measures, when applicable. The preferred method is to use biological controls or natural substances for controlling pests, plant diseases, and weeds on campus. This allows CSU to limit the type and quantity of chemical and other less desirable controls. If the use of chemicals is unavoidable, CSU uses less potent chemicals whenever possible. This SOP describes measures to minimize impact to stormwater from fertilizer and pest control activities. Conduct mixing in a location where a spill will not access a storm inlet or waterway Avoid excessive fertilizer application Store chemicals in the designated storage unit on South campus; the unit is equipped with secondary containment, security and signs. Always apply chemicals according to safety regulations and guidelines Do not apply chemicals during a rain storm or while the area is being irrigated Avoid over spraying onto sidewalks or roads. Do not apply to frozen ground When irrigating after application, do not allow water to run into streets and storm drains Dispose of waste chemicals in accordance with CSU s policies, contact Environmental Health Services (EHS) at for assistance. For cleanup of application equipment, first make sure tanks and sprayers are empty. Clean in the Vehicle Wash Bay, if necessary (floor drains go to sanitary sewer). Address any spills promptly. EHS are available to respond to spills and will conduct spill reporting, as necessary. Grounds Environmental Health Services SOP No A 12/15/09

11 14.9 Catch Basin Cleaning SOP No.: 14.9 SOP Name: Catch Basin Cleaning CSU uses an automatic work order system to periodically direct the Grounds Shop crew to clean out storm catch basins, inlets and other storm water conveyance systems. Many catch basins and inlets have a sump below the discharge pipe to collect sediment and other debris before it travels down the storm sewer system. A percentage of CSU catch basins and inlets are cleaned each year. In addition, plugged or problematic catch basins and inlets are cleaned as-needed. 1. Access each catch basin or inlet and visually evaluate the condition/contents. 2. If the catch basin/inlet is not a permitted confined space, proceed with cleaning out the debris using shovels. 3. Put all debris into bags or truck bed and dispose at the Hughes stadium south area, or CSU dumpsters. 4. Replace the lid and note any problems that need further attention (e.g. pipes appear clogged with sediment, or lid is broken). 5. Report problems to supervisor for follow-up. In addition to routine catch basin cleaning, CSU Utilities personnel perform or commission periodic storm sewer jetting and cleaning. Grounds SOP No B 12/15/09 A 9/4/08

12 14.10 Storm Sewer Jetting and Videotaping SOP No.: SOP Name: Storm Sewer Jetting and Videotaping CSU cleans and videotapes approximately 1,000 feet of storm sewer piping per year. The storm sewer pipe is jetted using a high pressure water wash to remove grease, sludge, tree roots, dirt and rocks which prevent proper flow of sewer lines. The storm sewer is then videotaped with a camera to look for breaks and obstructions in the pipe. After jetting and videotaping, Facilities personnel can prioritize and plan storm sewer pipe repairs. The following procedures are followed to minimize stormwater pollution: A vacuum truck is used to vacuum up the jetting water and debris simultaneously with jetting to minimize the amount of debris released downstream In order to avoid damaging the pipe, operators are required to understand the maximum working pressures to be used. CSU Facilities personnel coordinate with the jetting/cleaning contractor to discuss information about the pipe location, size, material, condition and repair history before starting work on the sewer pipe. Decanted liquid wastes with very little solids or oil sheen can be disposed of in the sanitary sewer. Solids can be transported to Hughes stadium where they can be discharged onto an unpaved surface near the southern portion of the land owned by CSU. At that location, the wastes dry out and liquid evaporates or infiltrates. The area is a large slightly concave gravel area that precludes runoff to nearby ditches or waterways. Utilities and Trades SOP No B 12/16/09 A 5/7/09

13 14.11 Street Sweeping SOP No.: SOP Name: Street Sweeping CSU contracts out street sweeping, typically on an annual basis. Paved streets and parking lots can be significant sources of pollutants in stormwater discharges. If not conducted properly, operation and maintenance practices can add to the pollution. This SOP has Best Management Practices (BMPs) intended to control the sweeping, collection and disposal of street sweeping wastes and to keep them out of stormwater. When contracting street sweeping services, please communicate the following requirements to the entity or personnel performing the street sweeping: Operate sweepers according to manufacturer s settings and standards. Use only clean and properly maintained equipment Use minimal water before sweeping. Spills should be immediately contained and treated. Decanted liquid wastes with very little solids or oil sheen can be disposed of in the sanitary sewer. Solids can be transported to Hughes stadium where they can be discharged onto an unpaved surface near the southern portion of the land owned by CSU. At that location, the wastese dry out and liquid evaporates or infiltrates. The area is a large slightly concave gravel area that precludes runoff to nearby ditches or waterways. Grounds SOP No B 12/16/09 A 5/7/09

14 14.12 Spill Response SOP No.: SOP Name: Spill Response CSU s Environmental Health Services (EHS) department maintains a spill response team, spill response vehicle and an updated Spill Prevention, Control and Countermeasure (SPCC) Plan. The following spill response procedures help reduce stormwater pollution due to chemical releases: CSU faculty, staff and students are instructed to call 911 (CSU Police Department) or CSU Dispatch in the event of a chemical spill. CSU faculty and staff periodically receive training in stormwater prevention due to spills Storage units containing chemicals that are stored outside, including tanks, drums and equipment, are periodically inspected by CSU personnel. Oil storage containers and equipment are inspected at least monthly in accordance with the SPCC Plan During inspections, the inspector checks for leaks, corrosion, structural damage and valve plugs on tanks, piping, and valves. The secondary containment structures are checked for the presence of stormwater, and emptied if partially full. If secondary containment structures contain stormwater, it is first checked for a sheen or floating oil, and if present the oil is removed and containerized for disposal/recycling. If no oil or sheen are present, then the water is drained or pumped to the ground outside the containment area. Chemical or oil loading and unloading operations are full-time attended and the area checked for spills or leaks following loading/unloading. EHS and/or the Stormwater Coordinator evaluate the conditions of each spill and, if it triggers reporting requirements, report according to applicable regulations. Each spill response is documented and maintained on file at EHS. EHS keeps the spill response vehicle equipped with absorbent booms, pads, granular absorbent, empty drums, brooms and shovels. Spill kits are maintained near select fueling operations and oil storage containers. Environmental Health Services SOP No A 9/4/08

15 14.13 Septic System Inspection SOP No.: SOP Name: Septic System Inspection CSU owns and operates one septic system within the MS4 boundary area. It is located on the south side of the Engineering Research Center (ERC) on Foothills Campus and serves two restrooms with a total of two toilets, two sinks and one urinal. Procedure: Stormwater pollution is minimized through the following procedures: The level of solids in the septic tank is checked every three years and pumped if necessary Signs are posted on the restroom doors warning users not to dispose of chemicals in the sewer The leach field area is visually observed at least once per year to check for seeps or leaching that could indicate system failure. ERC SOP No A 2/19/10

16 14.14 Hazardous Wastes Handling SOP No.: SOP Name: Hazardous Wastes Handling CSU s Environmental Health Services (EHS) department operates a hazardous waste management system, which includes training of generators, tracking of satellite accumulation areas, characterization, pick-up and staging for disposal of hazardous wastes. Hazardous wastes are bulked and staged at the Regulated Materials building on South Campus and disposed off-site by licensed transporters and disposal companies. See EHS webpage: The following stormwater pollution prevention practices and operations are in place to minimize impacts to stormwater from hazardous wastes: All satellite accumulation areas are indoors or under cover with secondary containment Hazardous waste containers are required to be properly labeled Researchers, faculty and CSU staff involved in generating hazardous wastes receive training in the proper handling and storage of hazardous wastes, including how to minimize and response to spills Hazardous wastes are picked up and transported in an enclosed truck The Regulated Materials building has a covered loading dock Personnel handling hazardous wastes receive and maintain Hazardous Waste Operations training EHS personnel are on call 24/7 for spill response If orphan containers of unknown wastes are discovered, the department who operates the area where the wastes are discovered is instructed and assisted by EHS in the proper storage, characterization and disposal of the waste. Wastes are required to be properly disposed of promptly. Environmental Health Services SOP No A 9/4/08

17 14.15 Irrigation System Adjustment and Maintenance SOP No.: SOP Name: Irrigation System Adjustment and Maintenance CSU adjusts and maintains its irrigation systems to minimize overspray and excessive irrigation that may lead to runoff of landscape care chemicals (fertilizers and pesticides) and/or movement of accumulated sediment and debris into storm drains. In order to maintain a safe and sustainable irrigation system adjustments and maintenance include: Operation of the system using computer programs to account for average rainfall and temperatures and automatically reducing or ceasing irrigation with the appropriate evapotranspiration requirement is reached. Watering at night to ensure optimal volume application and minimize muddy conditions during daytime foot traffic Visually checking system operations for correct timing and clogged or broken heads Unclogging heads as needed Making adjustments to spray patterns Checking lines for breaks Checking for proper coverage Seasonal Clock adjustments ( Start times, zone run times, watering days, etc) Rain Sensor operation In addition, the following stormwater pollution prevention measures are emphasized and implemented: Use of natural and biological, rather than chemical pest controls Periodic measurement of soil nutrients to optimize fertilizer application and avoid overapplication - Grounds SOP No A 5/7/09

18 14.16 BMP Maintenance SOP No.: SOP Name: BMP Maintenance Stormwater Best Management Practices (BMPs) are structures designed and operated to treat stormwater as it leaves an area. Construction BMPs are temporary methods used on construction sites, and permanent BMPs are part of a finished development and remain in place. This SOP describes CSU s practices for Permanent BMP maintenance. CSU owns and operates more than 50 permanent BMPs on Main, South and Foothills campuses, including detention ponds, rip rap, infiltration areas, grass swales, permeable pavers, bioswales and subgrade chambers. BMPs are designed to remove pollutants such as oil, sediment and nutrients. The structures must be maintained so they do not become overloaded with pollutants and release, rather than trap the pollutants they are intended to remove. CSU s stormwater personnel inspect at least 50% of the permanent BMPs each year If problems are observed, then the stormwater coordinator communicates with grounds, heavy equipment or labor crew personnel to plan and execute the required maintenance. If sediment that is removed from a BMP contains oily residue or other chemicals, it is containerized and disposed at the landfill. If removed sediment appears clean, it is transported to an area outside of the BMP and dumped or spread. Utilities, Grounds, Heavy Equipment, Labor Crew SOP No A 9/4/08

19 14.17 Fire Extinguisher Training SOP No.: SOP Name: Fire Extinguisher Training CSU employees and tenants conduct periodic fire extinguisher training which frequently involves discharging the contents of a fire extinguisher outside on a fire in a controlled exercise. Fire extinguisher contents depend on the extinguisher type but may include: sodium bicarbonate, ammonium phosphate, potassium bicarbonate, urea complex or foams. This SOP describes measures to minimize impact to stormwater from the discharged contents of fire extinguishers from training exercises. Plan the exercise so that safety is maximized and stormwater pollution in minimized Following the exercise sweep up all dry fire extinguisher materials as well as ash and any unburned solid fuels used of the exercise Do not wash the fire extinguisher materials down the gutter, drain or into a ditch or waterway. PLEASE SWEEP UP AFTER TRAINING Grounds Environmental Health Services SOP No A 12/18/09
