CITY OF EVERETT STORMWATER MANAGEMENT MANUAL
<br /> 5. Promptly repair or replace all leaking connections,pipes,hoses,valves,etc. which can
<br /> contaminate stormwater.
<br /> 6. Clean up pollutant liquid leaks and spills in impervious uncovered containment areas at the end of
<br /> each working day.
<br /> 7. Use solid absorbents,e.g.,clay and peat absorbents and rags for cleanup of liquid spills/leaks,
<br /> where practicable.
<br /> 8. Recycle materials,such as oils, solvents, and wood waste,to the maximum extent practicable.
<br /> Preventative Maintenance
<br /> 1. Prevent the discharge of unpermitted liquid or solid wastes,process wastewater,and sewage to
<br /> ground or surface water,or to storm drains which discharge to surface water,or to the ground.
<br /> 2. Do not connect floor drains in potential pollutant source areas to storm drains,surface water,or to
<br /> the ground.
<br /> 3. Conduct all oily parts cleaning,steam cleaning,or pressure washing of equipment or containers
<br /> inside a building, or on an impervious contained area,such as a concrete pad.Direct
<br /> contaminated stormwater from such an area to a sanitary sewer where allowed by the City, or to
<br /> other approved treatment.
<br /> 4. Do not pave over contaminated soil unless it has been determined that ground water has not been
<br /> and will not be contaminated by the soil. Call Ecology for assistance.
<br /> 5. Construct impervious areas that are compatible with the materials handled. Portland cement
<br /> concrete,asphalt, or equivalent material may be considered.
<br /> 6. Use drip pans to collect leaks and spills from industrial/commercial equipment such as cranes at
<br /> ship/boat building and repair facilities, log stackers, industrial parts,trucks and other vehicles,
<br /> which are stored outside.
<br /> 7. At industrial and commercial facilities,drain oil and fuel filters before disposal.Discard empty
<br /> oil and fuel filters,oily rags and other oily solid waste into appropriately closed and properly
<br /> labeled containers,and in compliance with the Uniform Fire Code.
<br /> 8. For the storage of liquids use containers, such as steel and plastic drums,that are rigid and
<br /> durable,corrosion resistant to the weather and fluid content,non-absorbent,water tight,rodent-
<br /> proof, and equipped with a close fitting cover.
<br /> 9. For the temporary storage of solid wastes contaminated with liquids or other potential pollutant
<br /> materials use dumpsters,garbage cans, drums and comparable containers,which are durable,
<br /> corrosion resistant,non-absorbent,non-leaking, and equipped with either a solid cover or screen
<br /> cover to prevent littering. If covered with a screen,the container must be stored under a lean-to
<br /> or equivalent structure.
<br /> 10. Where exposed to stormwater,use containers,piping,tubing,pumps, fittings,and valves that are
<br /> appropriate for their intended use and for the contained liquid.
<br /> 11. Where feasible, store potential stormwater pollutant materials inside a building or under a cover
<br /> and/or containment.
<br /> 12. Minimize use of toxic cleaning solvents, such as chlorinated solvents, and other toxic chemicals.
<br /> 13. Use environmentally safer raw materials,products, additives,etc. such as substitutes for zinc used
<br /> in rubber production.
