During Construction

Don’t mix up more fresh concrete or cement than you will use in a two-hour period.

Set up and operate small mixers on tarps or heavy plastic drop cloths.

When cleaning up after driveway or sidewalk construction, wash �nes onto dirt areas, not down the driveway or into the street or storm drain.

Protect applications of fresh concrete and mortar from rainfall and runo� until the material has dried.

Wash down exposed aggregate concrete only when the wash water can (1) �ow onto a dirt area; (2) drain onto a bermed surface from which it can be pumped and disposed of properly; or (3) be vacuumed from a catchment created by blocking a storm drain inlet. If necessary, divert runo� with temporary berms. Make sure runo� does not reach gutters or storm drains.

When breaking up pavement, be sure to pick up all the pieces and dispose of properly. Recycle large chunks of broken concrete at a local recycling facility.

Never bury waste material. Dispose of small amounts of excess dry concrete, grout, and mortar in the trash.

Never dispose of washout into the street, storm drains, drainage ditches, or streams.

Doing the Job Right General Business Practices

Wash out concrete mixers only in designated wash-out areas in your yard, away from storm drains and waterways, where the water will �ow into a temporary waste pit in a dirt area.

Let water percolate through soil and dispose of settled, hardened concrete as garbage. Whenever possible, recycle washout by pumping back into mixers for reuse.

Wash out chutes onto dirt areas at site that do not �ow to streets or drains.

Always store both dry and wet materials under cover, protected from rainfall and runo� and away from storm drains or waterways. Protect dry materials from wind.

Secure bags of cement after they are open. Be sure to keep wind-blown cement powder away from streets, gutters, storm drains, rainfall, and runo�.

Do not use diesel fuel as a lubricant on concrete forms, tools, or trailers.

• Concrete Delivery/Pumping Workers

Storm Drain Pollution from Fresh Concrete And Mortar Applications

Fresh concrete and cement-related mortars that wash into lakes, streams, or estuaries are toxic to �sh and the aquatic environment. Disposing of these materials to the storm drains or creeks can block storm drains, causes serious

Heavy Equipment Operation

Who should use this information?

• Vehicle and Equipment Operators

• Site Supervisors

• General Contractors

• Home Builders

Site Planning and Preventive Vehicle Maintenance

Designate one area of the construction site, well away from streams or storm drain inlets, for auto and equipment parking, refueling, and routine vehicle and equipment maintenance. Contain the area with berms, sand bags, or other barriers.

Maintain all vehicles and heavy equipment. Inspect frequently for and repair leaks.

Perform major maintenance, repair jobs, and vehicle and equipment washing o� site where cleanup is easier.

If you must drain and replace motor oil, radiator coolant, or other �uids on site, use drip pans or drop clot hs to catch drips and spills. Collect all spent �uids, store in separate containers. Recycle them wherever possible, otherwise, dispose of them as hazardous wastes.

Do not use diesel oil to lubricate equipment parts, or clean equipment.

Use only water for any onsite cleaning.

Cover exposed �fth wheel hitches and other oily or greasy equipment during rain events.

Use as little water as possible for dust control. Ensure water used doesn’t leave silt or discharge to storm drains.

Spill Cleanup

Clean up spills immediately when they happen.

Never hose down "dirty" pavement or impermeable surfaces where �uids have spilled. Use dry cleanup methods (absorbent materials, cat litter, and/ or rags) whenever possible and properly dispose of absorbent materials.

Sweep up spilled dry materials immediately. Never attempt to “wash them away" with water, or bury them.

Clean up spills on dirt areas by digging up and properly disposing of contaminated soil.

Report signi�cant spills to the appropriate local spill response agencies immediately. In Milpitas, dial 9-1-1 if hazardous materials might enter the storm drain.

Stormwater Pollution from Heavy Equipment on Construction Sites

Poorly maintained vehicles and heavy equipment that leak fuel, oil, antifreeze or other �uids on the construction site are common sources of storm drain pollution.

Prevent spills and leaks by isolating equipment from runo� channels, and by watching for leaks and other maintenance problems. Remove construction equipment from the site as soon as possible.

Earth-Moving and Dewatering Activities

Who should use this information?

• Bulldozer, Back Hoe, and Grading Machine Operators

• Dump Truck Drivers

• Site Supervisors

• General Contractors

• Home Builders

• Developers

Doing the Job Right General Business Practices

Schedule excavation and grading work during dry weather.

Perform major equipment repairs away from the job site.

When refueling or vehicle/equipment maintenance must be done on site, designate a location away from storm drains.

Do not use diesel oil to lubricate equipment parts, or clean equipment.

Practices During Construction Remove existing vegetation only when absolutely necessary. Plant temporary vegetation for erosion control on slopes or where construction is not immediately planned.

Protect downslope drainage courses, streams, and storm drains with wattles, or temporary drainage swales. Use check dams or ditches to divert runo� around excavations. Refer to the Regional Water Quality Control Board’s Erosion and Sediment Control

Field Manua l for proper erosion and sediment control measures, and California Stormwater Quality Association Stormwater Best Management Practice Handbook (construction, 2003) Cover stockpiles and excavated soil with secured tarps or plastic sheeting.

Dewatering Operations Check for Toxic Pollutants

Check for odors, discoloration, or an oily sheen on groundwater.

Call your local wastewater treatment agency and ask whether the groundwater must be tested.

If contamination is suspected, have the water tested by a certi�ed laboratory.

Depending on the test results, you may be allowed to discharge pumped groundwater to the storm drain (if no sediments present) or sanitary sewer.

OR, you may be required to collect and haul pumped groundwater o�site for treatment and disposal at an appropriate treatment facility.

Storm Drain Pollution from Earth-Moving Activities

Soil excavation and grading operations loosen large amounts of soil that can �ow or blow into storm drains when handled improperly. Sediments in runo� can clog storm drains, smother aquatic life, and destroy habitats in creeks and the Bay.

E�ective erosion control practices reduce the amount of runo� crossing a site and slow the �ow with check dams or roughened ground surfaces.

Contaminated groundwater is a common problem in the Santa Clara Valley. Depending on soil types and site history, groundwater pumped from construction sites may be contaminated with toxics (such as oil or solvents) or laden with sediments. Any of these pollutants can harm wildlife in creeks or the Bay, or interfere with wastewater treatment plant operation. Discharging sediment-laden water from a dewatering site into any water of the state without treatment is prohibited.

General Business Practices

Develop and implement erosion/sediment control plans for roadway embankments.

Schedule excavation and grading work during dry weather.

Check for and repair leaking equipment.

Perform major equipment repairs at designated areas in your maintenance yard, where cleanup is easier. Avoid performing equipment repairs at construction sites.

When refueling or when vehicle/equipment maintenance must be done on site, designate a location away from storm drains and creeks.

Do not use diesel oil to lubricate equipment parts or clean equipment.

Recycle used oil, concrete, broken asphalt, etc.

whenever possible, or dispose of properly.

During Construction

Avoid paving and seal coating in wet weather, or when rain is forecast, to prevent fresh materials from contacting stormwater runo�.

Cover and seal catch basins and manholes when applying seal coat, slurry seal, fog seal, or similar materials.

Protect drainage ways by using earth dikes, sand bags, or other controls to divert or trap and �lter runo�.

Never wash excess material fr om exposed aggregate concrete or similar treatments into a street or storm drain. Collect and recycle, or dispose to dirt area.

Cover stockpiles (asphalt, sand, etc.) and other construction materials with plastic tarps. Protect from rainfall and prevent runo� with temporary roofs or plastic sheets and berms.

Park paving machines over drip pans or absorbent material (cloth, rags, etc.) to catch drips when not in use.

Clean up all spills and leaks using “dry” methods (with absorbent materials and/or rags) Dig up, remove, and properly dispose of contaminated soil.

Storm Drain Pollution from Roadwork

Road paving, surfacing, and pavement removal happen right in the street, where there are numerous opportunities for asphalt, saw-cut slurry, or excavated material to illegally enter storm drains. Extra planning is required to store and dispose of materials properly and guard against pollution of storm drains, creeks, and the Bay.

Detecting Contaminated Soil or Groundwater

Contaminated groundwater is a common problem in the Santa Clara Valley. It is essential that all contractors and subcontractors involved know what to look for in detecting contaminated soil or groundwater, and testing ponded groundwater before pumping. Watch for any of these conditions:

1. Unusual soil conditions, discoloration or odor.

2. Abandoned under-ground tanks.

3. Abandoned wells.

4. Buried barrels, debris or trash.

If any of these are found follow the procedures below.

Collect and recycle or appropriately dispose of excess abrasive gravel or sand.

Avoid over-application by water trucks for dust control.

Asphalt/Concrete Removal

Avoid creating excess dust when breaking asphalt or concrete.

After breaking up old pave ment, be sure to remove all chunks and pieces. Make sure broken pavement does not come in contact with rainfall or runo�.

When making saw cuts, use as little water as possible. Shovel or vacuum saw-cut slurry and remove from the site. Cover or protect storm drain inlets during saw-cutting. Sweep up, and properly dispose of, all residues.

Sweep, never hose down streets to clean up tracked dirt. Use a street sweeper or vacuum truck. Do not dump vacuumed liquor in storm drains.

Handling Paint Products

Keep all liquid paint products and wastes away from the gutter, street, and storm drains. Liquid residues from paints, thinners, solvents, glues, and cleaning �uids are hazardous wastes and must be disposed of as hazardous.

Wash water from painted buildings constructed before 1978 can contain high amounts of lead, even if paint chips are not present. Before you begin stripping paint or cleaning pre-1978 building exteriors with water under high pressure, test paint for lead by taking paint scrapings to a local laboratory. See Yellow Pages for a state-certi�ed laboratory.

If there is loose paint on the building, or if the paint tests positive for lead, block storm drains.

Check with the wastewater treatment plant to determine whether you may discharge water to the sanitary sewer, or if you must send it o�site for disposal as hazardous waste.

Paint Removal

Paint chips and dust from non-hazardous dry stripping and sand blasting may be swept up or collected in plastic drop cloths and disposed of as trash.

Chemical paint stripping residue and chips and dust from marine paints or paints containing lead, mercury or tributyl tin must be disposed of as hazardous wastes. Lead based paint removal requires a state-certi�ed contractor.

When stripping or cleaning building exteriors with high-pressure water, block storm drains. Direct wash water onto a dirt area to �nd out if you can collect (mop or vacuum) building cleaning water and dispose to the sanitary sewer. Sampling of the water may be required to assist the wastewater treatment authority in making its decision.

Painting Cleanup

Never clean brushes or rinse paint containers into a street, gutter, storm drain, French drain, or stream.

For water-based paints, paint out brushes to the extent possible, and rinse into a drain that goes to the sanitary

Storm Drain Pollution from Paints, Solvents, and Adhesives

All paints, solvents, and adhesives contain chemicals that are ha rmful to wildlife in local creeks, San Francisco Bay, and the Paci�c Ocean. Toxic chemicals may come from liquid or solid products or from cleaning residues or rags. Paint material and wastes, adhesives and cleaning �uids should be recycled when possible, or disposed of properly to prevent these materials from �owing into storm drains and watercourses.

Doing the Job Right General Business Practices Protect stockpiles (e.g. asphalt, sand, or soil) and landscaping materials from wind and rain by storing them under tarps or secured plastic sheeting.

Store pesticides, fertilizers, and other chemicals indoors or in a shed or storage cabinet.

Schedule grading and excavation projects during dry weather.

Use temporary check dams or ditches to divert runo� away from storm drains.

Protect storm drains with sandbags or other sediment controls.

Revegetation is an excellent form of erosion control for any site. Replant as soon as possible with temporary vegetation such as grass seed.

Landscaping/Garden Maintenance Consider using Integrated Pest Management Techniques.

Use pesticides sparingly, according to instructions on the label. Rinse empty containers, and use rinsewater as product. Dispose of rinsed, empty containers in the trash.

Dispose of unused pesticides as hazardous waste.

Collect lawn and garden clippings, pruning waste, and tree trimmings. Chip if necessary, and compost if possible.

Do not blow or rake leaves, etc. into the street, or place yard waste in gutters or on dirt shoulders.

Sweep up any leaves, litter or residue in gutters or on street.

Swimming Pool Maintenance

Many landscaping activities expose soils and increase the likelihood that earth and garden chemicals will run o� into the storm drains during irrigation or when it rains. Swimming pool water containing chlorine and copper-based algaecides should never be discharged to storm drains. These chemicals are toxic to aquatic life.

sewer. Never pour paint down a storm drain. Dispose of excess liquids and residue as hazardous waste.

For oil-based paints, paint out brushes to the extent possible and clean with thinner or solvent in a proper container. Filter and reuse thinners and solvents. Dispose of excess liquids and residue as hazardous waste.

When thoroughly dry, empty paint cans, used brushes, rags, and drop cloths may be disposed of as garbage in a sanitary land�ll. Leave lids o� paint cans so the refuse collector cam see that they are empty. Empty, dry paint cans also may be recycled as metal.

Dispose of empty aerosol paint cans as hazardous waste or at household hazardous waste collection events.

Recycle/Reuse Leftover Paints Whenever Possible

Donate excess water-based (latex) paint for reuse.

Reuse leftover oil-based paint. Dispose of non-recyclable thinners, sludge and unwanted paint, as hazardous waste.

Unopened cans of paint may be able to be returned to the paint vendor. Check with the vendor regarding its "buy-back" policy.

Never discharge pool or spa water to a street or storm drain; discharge to a sanitary sewer cleanout.

If possible, when emptying a pool or spa, let chlorine dissipate for a few days and then recycle/ reuse water by draining it gradually onto a landscaped area. OR

San Jose/Santa Clara Water Pollution Control Plant (408) 945-5300. You may be able to discharge to the sanitary sewer by running the hose to a utility sink or sewer pipe clean-out.

Do not use copper-based algaecides Control algae with chlorine or other alternatives, such as sodium bromide.

Filter Cleaning

Never clean a �lter in the street or near a storm drain. Rinse cartridge and diatomaceous earth �lters onto a dirt area, and spade �lter residue into soil. Dispose of spent diatomaceous earth in the garbage.

If there is no suitable dirt call San Jose/Santa Clara Water Pollution Control Plant (408) 945-5300 for instructions on discharging �lter backwash or rinse water to the sanitary sewer.

General Principles

Keep an orderly site and ensure good housekeeping practices are used.

Maintain equipment properly.

Cover materials when they are not in use.

Keep materials away from streets, storm drains and drainage channels.

Ensure dust control water doesn’t leave site or discharge to storm drains.

Advance Planning To Prevent Pollution

Schedule excavation and grading activities for dry weather periods. To reduce soil erosion, plant temporary vegetation or place other erosion controls before rain begins. Use the Erosion and Sediment Control Field Manual , available form the Regional Water Quality Control Board San Francisco Bay Region, as a reference.

Control the amount of runo� crossing your site (especially during excavation!) by using berms or temporary or permanent drainage ditches to divert water �ow around the site. Reduce stormwater runo� velocities by constructing temporary check dams or berms where appropriate.

Good Housekeeping Practices

Designate one area of the site for auto parking, vehicle refueling, and routine equipment maintenance. The designated area should be well away from streams or storm drain inlets, bermed if necessary. Make major repairs o� site.

Keep materials out of the rain – prevent runo� contamination at the source. Cover exposed piles of soil or construction materials with plastic sheeting or temporary roofs. Before it rains, sweep and remove materials from surfaces that drain to storm drains, creeks, or channels.

Keep pollutants o� exposed surfaces. Place trash cans and recycling receptacles around the site to minimize litter.

Clean up leaks, drips and other spills immediately so they do not contaminate soil or groundwater or leave residue on paved surfaces.

Never hose down “dirty” pavement or surfaces where materials have spilled.

Use dry cleanup methods whenever possible. If you must use water, use just enough to keep the dust down.

Cover and maintain dumpsters. Check frequently for leaks.

Place dumpsters under roofs or cover with tarps or plastic sheeting secured around the outside of the dumpster.

Never clean out a dumpster by hosing it down on the construction site.

Storm Drain Pollution from Construction Activities

Construction sites are common sources of storm water pollution. Materials and wastes that blow or wash into a storm drain, gutter, or street have a direct impact on local creeks and the Bay.

As a contractor, or site supervisor, owner or operator of a site, you may be responsible for any environmental damage caused by your subcontractors or employees.

Preventing Pollution: It’s Up to Us

In the Santa Clara Valley, storm drains transport water directly to local creeks and San Francisco Bay without treatment. Stormwater pollution is a serious problem for wildlife dependent on our creeks and bays and for the people who live near polluted streams or baylands. Common sources of this pollution include spilled oil, fuel, and �uids from vehicles and heavy equipment; construction debris; sediment created by erosion; landscaping runo� containing pesticides or weed killers; and materials such as used motor oil, antifreeze, and paint products that people pour or spill into a street or storm drain.

Thirteen valley municipalities have joined together with Santa Clara County and the Santa Clara Valley Water District to educate local residents and businesses and �ght stormwater pollution. This “blueprint” summarizes “Best Management Practices “(BMPs) for stormwater pollution prevention.

Spill Response Agencies:

Small Business Hazardous Waste Disposal Program

Santa Clara County businesses that generate less than 27 gallons or 220 pounds of hazardous waste per month are eligible to use Santa Clara County’s Small Business Hazardous Waste Disposal Program. Call (408) 299-7300 for a quote, more information or guidance on disposal.

BLUEPRINT FOR A CLEAN BAY

Best Management Practices for the Construction Industry

Remember: The property owner and the contractor share ultimate responsibility for the activities that occur on a construction site. You may be held responsible for any environmental damage caused by your subcontractors or employees.

Place portable toilets away from storm drains. Make sure portable toilets are in good working order. Check frequently for leaks .

Materials/Waste Handling

Practice Source Reduction -- minimize waste when you order materials. Order only the amount you need to �nish the job.

Use recyclable materials whenever possible. Arrange for pick-up of recyclable materials such as concrete, asphalt, scrap metal, solvents, degreasers, cleared vegetation, paper, rock, and vehicle maintenance materials such as used oil, antifreeze, batteries, and tires.

Permits In addition to local grading and building permits, you will need to obtain coverage under the State's General Construction Activity Stormwater Permit if your construction site's disturbed area totals 1 acre or more. Information on the General Permit can be obtained from the Regional Water Quality Control Board.

(b) Judicial Civil Penalties. Any person who intentionally or negligently violates any provision of this Chapter or any provision of any permit or certi�cate issued pursuant to this Chapter shall be civilly liable to the city in a sum not to exceed twenty-�ve thousand dollars per day for each day in which such violation occurs.

(c) Administrative Citations. When the City Manager and/or his or her designee determines that one or more violations of this Chapter have occurred an administrative citation may be issued pursuant to the procedures set forth in Sections V-500-8.00 through V-500-8.06. The schedule of �nes for administrative citations issued for violations of this Chapter shall be set forth in the schedule of �nes established by resolution of the City Council.

(d) Notice of Noncompliance. If the severity of the violation warrants immediate action, a Notice of Noncompliance or Stop Work Notice shall be issued, permits may be suspended or revoked, Stormwater Pollution Prevention Plans may be found in noncompliance, and corrective actions may be implemented in accordance with Section 11 of this Chapter. For all other cases, including those sites or projects where a stormwater pollution prevention plan is not required, the City Manager or his or her designee shall issue a Notice of Noncompliance that shall enumerate the violations found. The City Manager or his or her designee shall order compliance by a date or hour certain at his or her discretion. If the violations are not abated in the time period identi�ed in the Notice of Noncompliance, the site shall be deemed to be in noncompliance with federal, State and local laws and the City Manager or his or her designee shall have the authority to issue a Stop Work Notice and/or deem the Stormwater Pollution Prevention Plan inadequate. If a Stop Work Notice is issued, corrective actions must be performed until the site has achieved compliance. Corrective actions may include revision and resubmission of any Plan, including, but not limited to, Stormwater Pollution Prevention Plan, Erosion Control Plan or Grading Plan. The City Manager or his or her designee may also require a discharger that has violated any discharge limits contained in this Chapter to install a temporary system for the capture, testing, and release of stormwater.

(e) Suspension of Utility Service. The City may, without prior notice, suspend water service, sanitary sewer service, and/or storm drain discharge access to a person discharging to the storm drain system when such suspension is necessary to stop an actual or threatened discharge which presents, or may present, imminent and substantial danger to the environment or to the health or welfare of persons; or presents, or may present, imminent and substantial danger to the storm drain system.

XI-16-11 Accidental Discharge

- Noti�cation of Discharge

(a) All persons shall notify the City by telephone immediately by dialing 911 upon accidentally discharging any material other than an acceptable discharge into a storm drain or watercourse to enable countermeasures to be taken by the City to minimize damage to storm drains and the receiving waters. Prohibited discharges include but are not limited to:

(1) Sewage;

(2) Discharges of wash water resulting from the cleaning of exterior surfaces and pavement, or the equipment and other facilities of any commercial business, or any other public or private facility;

(3) Discharges of runo� from material storage areas, including containing chemicals, fuels, or other potentially polluting or hazardous materials;

(4) Discharges of pool or fountain water containing chlorine, biocides, or other chemicals; discharges of pool or fountain �lter backwash water;

(5) Discharges of sediment, pet waste, vegetation clippings, or other landscape or construction-related wastes; and

(6) Discharges of food-related wastes (e.g., grease, �sh processing, and restaurant kitchen mat and trash bin wash water, etc.).

The City, at its sole option, may direct the person or persons responsible for the discharge to perform cleanup activities when it is deemed by the City that the person or persons have the capability to perform such activities. All violations shall be corrected in a timely manner before the next rain event, but no longer than ten

(10) business days after the violations are discovered.

(b) The person deemed by the City responsible for the discharge shall, within �ve (5) days of the date of occurrence, provide a detailed written statement to the City Manager or his or her designee describing the causes of the accidental discharge and the measures being taken to prevent future occurrences.

Such noti�cation will not relieve persons of liability for violations of this Chapter or for any �nes imposed on the City on account thereof under Section 13350 of the California Water Code, or for violation of Section 5650 of the California Fish and Wildlife Code, or any other applicable provisions of State or federal law.

(c) Persons deemed by the City responsible for the discharge are responsible for all expenses resulting from the discharge, including, but not limited to, damages, �nes, and costs of clean-up, whether performed by their own e�orts, City e�orts, or the e�orts of a third party. Reimbursement of City e�orts shall be determined by the number of personnel required and amount of time necessary for the coordination of City e�orts and actual clean-up. All personnel costs shall be charged at their current fully-burdened rate, including overtime, plus any and all other direct costs.

Local Pollution Control Agencies

When it’s time to drain a pool, spa, or fountain, please be sure to call your local wastewater treatment plant before you start for further guidance on �ow rate restrictions, back�ow prevention, and handling special cleaning waste (such as acid wash). Discharge �ows should be kept to the low levels typically possible through a garden hose.

Higher �ow rates may be prohibited by local ordinance.

Milpitas Municipal Code (MMC) 2017

Supervision

Train your employees and subcontractors. Make these brochures available to everyone who works on the construction site. Inform subcontractors about the stormwater requirements and their own responsibilities.

Dispose of all wastes properly. Many construction materials and wastes, including solvents, water-based paints, vehicle �uids, broken asphalt and concrete, wood, and cleared vegetation can be recycled.

Materials that cannot be recycled must be taken to an appropriate land�ll or disposed of as hazardous waste.

Never bury waste materials or leave them in the street or near a creek or stream bed.

(f ) For construction projects where a total of three or more Stop Work Notices and Notices of Noncompliance for urban runo� violations have been issued, the City Manager or his or her designee may require the contractor to hire a Quali�ed SWPPP Developer (QSD) or Quali�ed SWPPP Practitioner (QSP) within three business days. The QSD/QSP shall establish e�ective BMPs, provide guidance for improvement for the duration of the project, and certify compliance. A Stop Work Notice shall be issued for failure to comply.

(g) Remedies Cumulative. The remedies provided in this section are cumulative and not exclusive, and shall be in addition to any other penalty provided for in this Chapter and shall be in addition to all other remedies available to the City under State and federal law.
