1 MUNICIPAL MAINTENANCE City of Brentwood

2 MUNICIPAL MAINTENANCE QUALITATIVE RESULTS Municipality: City of Brentwood Permit Year: (2008/2009) Introduction: The goal of the City of Brentwood s ( City ) Municipal Maintenance Performance Standards are to optimize pollutant removal during routine maintenance activities, such as street sweeping, maintenance of storm drain facilities, and minimizing discharges to storm drains and water courses from construction activities and road/landscaping maintenance activities through coordination and interdepartmental cooperation. The City s Public Works Department is comprised of eight (8) individuals responsible for implementation of the Municipal Maintenance Performance Standards. The City s Parks and Recreation Department includes five (5) individuals and two (2) maintenance firms responsible for implementation of the Municipal Maintenance Performance Standards. The principal contact person for all Municipal Maintenance activities related to permit compliance is Chris Ehlers, Deputy Director of Public Works, (925) Those responsible for implementation of Performance Standards attend frequent training workshops and/or conferences to understand the most recent permit requirements and relevant best management practice ( BMP ) technology to reduce or eliminate pollutant discharges with and without stormwater flows. Various Public Works staff regularly participates in the Municipal Maintenance Planning Work Group, depending upon the relevance of topics on the agenda and staff availability. Implementation & Evaluation: The City s Public Works Department mechanically sweeps each curbed street biweekly. Heavily traveled bike paths and vehicular thoroughfares are often swept twice a week. During the reporting period, the City s Public Works Department swept at least 18,031 miles of curbed street accounting for 2,047 cubic yards (cy) of material prevented from entering the City's storm drain system, including.07 of a pound of PCBs,.14 of a pound of Mercury, pounds of Copper, pounds of Lead, pounds of Nickel, pounds of Zinc, 5, pounds of total petroleum hydrocarbons and 10, pounds of oil and grease. The City has three (3) sweepers in service at this time. The oldest sweeper is seven (7) years and the newest is one (1) year old. The Fleet Maintenance Division of the Public MUNI - 1

3 Works Department performs scheduled preventative maintenance on the City-owned street sweeping equipment. The preventative maintenance schedule continues as follows: Rear engine is serviced every forty-five (45) days Front engine and chassis is serviced every ninety (90) days In order to ensure proper operation of the street sweeping equipment, the street sweeper operator frequently adjusts the broom and head, spring tension and mirrors to ensure a thorough sweeping. The street sweeping equipment does not have a weight on the main and gutter brooms; instead they are adjusted with spring tension. Street sweeper operators report landscape that interferes with street sweeping to their supervisor. City-owned landscape issues are passed to the Parks and Recreation Department and if the landscape is owned by a resident they are notified of the need to correct the condition. If a street sweeper breaks down, the route is still completed by other street sweeper operators. The City s bi-weekly schedule is consistently maintained. The City s interactive street sweeping schedule is posted on the City s website at the following address: Moreover, if a customer does not have access to the Internet they are encouraged to call the Public Works Administration office to obtain their street sweeping schedule. The City has an Autumn Leaf Bay Program that helps minimize the impact of leaf drop during the fall season. Operating from October 1 through the end of January, the program provides residents free leaf bags which can be picked up at the Utility Billing office. Customers can fill the bags with extra leaves and place them curbside next to their yard waste cart. They are collected on the yard waste pickup days at no additional charge. Moreover, if a street is heavy with leaf fall or debris, street sweeper operators will make several passes to clean the street (Refer to Attachment MM- 1 for a copy of the flyer). Street sweeping debris is deposited on the pavement at the solid waste transfer station and is then picked up and placed in a disposal bin. All storm drain inlets at the solid waste transfer station carry discharge material to the evaporation ponds at the wastewater treatment plant. Storm Drainage Facility Inspection & Maintenance Every catch basin, storm drain inlet and culvert within the City s jurisdiction is cleaned annually and before the start of the rainy season. The number of publicly-owned storm drain facilities inspected and cleaned by the Public Works Department includes 5,034 inlets, 27 culverts, 1 V-ditch and 1 pump station. From cleaning the facilities during the reporting period, staff removed 1,560 cubic yards of material from inlets and 174 cubic yards from culverts. From the materials removed, there was pounds of Copper, pounds of Lead, pounds of Zinc, 3, pounds of total petroleum MUNI - 2

4 hydrocarbons, and 9, pounds of oil and grease. All of the publicly-owned storm drain facilities are identified and tracked on a grid map for inspection and maintenance. There are six (6) areas that were identified and are targeted for more frequent inspections and cleanings due to higher volume of trash and leaf debris. These areas are the Arroyo-Seco Estates development, Marsh Creek Vista development, Applewood development, Brentwood Villa development, Downtown area, and the Southwood Homes development. These areas account for 103 inlets that are targeted for more frequent inspections and cleanings. The City owns two (2) combination jetter/vacuum trucks, mid- and large-size, to clean storm drain inlets, manholes, and sanitary sewer laterals. These trucks are invaluable in emergency situations. Material cleaned from catch basins, storm drain inlets and culverts is documented and then taken to the solid waste transfer station for disposal. All storm drains at the solid waste transfer station carry discharge material to the evaporation ponds at the wastewater treatment plant. Public Works Department vehicles have spill kits as part of their standard operating equipment. Employees can respond to spills and are trained to follow the Department of Public Works, Corporation Yard written Hazardous Materials Business Plan. The Plan is reviewed and updated annually as needed. The Plan is sent to the Contra Costa Health Services, Hazardous Materials Program, as part of reporting packages required of sites with predetermined quantities of hazardous chemicals or waste. Attachment for the Hazardous Materials Business Plan was included in the fiscal year 06/07 report. Litter Control The City removed tons of garbage, 8.66 tons of recycled material, 2.14 tons of metal/ferrous steel, 3.57 tons of wood, and tons of yard waste from our parks. This equates to a total of tons of potential pollutants diverted from the environment. The Public Works Street Maintenance Division removed 354 yards of litter from various areas throughout the City where garbage/materials were dumped alongside roadways or vacant fields/lots. The Street Maintenance Division also cleared roadways of garbage/items that had fallen from vehicles. The materials are loaded into various size trucks and taken to the solid waste transfer station for proper disposal. The City has been operating its own Solid Waste Division since 1994 and the solid waste transfer station since Garbage is collected weekly, and yard waste and recyclables are collected every other week. The collection program has been a leader in the County's recycling efforts with its innovative, user-friendly, containerized recycling programs. The City of Brentwood was one of the first cities in the County and the State to implement city-wide yard waste collection, and the single-stream recycling collection. MUNI - 3

5 The Solid Waste Division is operated financially as a separate entity, called an Enterprise Fund. All operational and administrative expenses are covered 100% by the fees collected for trash services. This ensures a fully self-sufficient operation, separate from the General Fund. The Solid Waste Division has distributed literature to residents and businesses to encourage recycling efforts. These include the following brochures: Attachment MM-2 1. Chemistry 101: Mixing chemicals makes for unpredictable results 2. Protect Your Home and Family From Mercury Contamination 3. Contra Costa Reuse & Recycling Guide (available as a link from website) Brentwood Solid Waste Service Guide Numbers 1 3 were also provided to customers in reporting period of fiscal year 05/06 and copies were included in that annual report. Many other reuse and recycling options and resources are available from the City s website at the following link: Also refer to the PEIO section for other public outreach material distributed with respect to litter control. Graffiti Abatement Practices The City s graffiti abatement is conducted on a call-out work order basis by the Public Works Department Street Maintenance Division and Code Enforcement. There was 22,289 square feet of graffiti removed during the reporting period. Depending upon the writing material used and the magnitude of offensiveness, the graffiti is either painted over, scrubbed, power washed, steam cleaned or if on a standard sign, the sign panel is replaced. If power washing or steam cleaning is necessary, it will generally only be performed on a wall offset from a paved area within a planter or dirt area. Sidewalks are usually steam cleaned. Any adjacent drainage inlets are protected with filter fabric and/or visqueen sheets. If a large volume of water with cleaning solutions are used which flows to an impervious surface, it is vacuumed up with the vactor trailer and disposed of in the evaporation basin. The dry material is later disposed of in the appropriate solid waste containers at the City s solid waste transfer station. Occasionally, graffiti will be spray painted over when it is on City-owned large metal bins. With the City s own plastic disposal and recycling carts, a Simple Green solution is tried first and if that does not work, the cart is brought into the yard for pressure washing. City carts are never pressure washed in the field. All storm drain inlets within the solid waste transfer station drain directly to evaporation ponds at the wastewater treatment plant. MUNI - 4

6 General Practices for Road Repair and Maintenance The City s road repair and maintenance are conducted by the Public Works Department Street Maintenance Division. Stormwater quality protection practices are addressed in the following manner: 1. Excavation and road maintenance activities are scheduled for dry weather, if feasible. 2. Major equipment repairs are performed at the Fleet Maintenance shop. 3. A location away from storm drain inlets and creeks is used when refueling or maintaining vehicles and equipment on-site. 4. Used motor oil, diesel oil, concrete, broken asphalt, etc., are recycled whenever possible. 5. Proper containment of diesel fuel used to lubricate or clean equipment or parts is practiced. 6. Employees are trained in using these general practices for road repair and maintenance activities. 7. Storm drain inlets are protected prior to breaking up asphalt or concrete. After every job, a street sweeper makes several passes to clean the street. The City very rarely hoses the street down. This would only occur under extenuating circumstances where a dirt shoulder exists. 8. Storm drain inlets are blocked or bermed prior to saw-cutting pavement using sandbags or an equivalent filter device, or absorbent materials such as pads, pillows and socks to contain slurry. Slurry is vacuumed during saw-cutting operations. If slurry somehow enters the storm drain system the material is removed to the maximum extent practicable. 9. The stockpiling of materials (asphalt materials, sand, etc.) in streets, gutter areas or near storm drain inlets or creeks is prohibited unless these areas are protected. The City rarely stockpiles material on the job site. As a general practice, all dig out material is hauled away immediately. Concrete and asphalt spoils are taken to the yard where a trucking company hauls it off to the recycle plant. 10. Storm drain openings are protected before applying seal coat, slurry seal, etc. Material is protected to the maximum extent practicable from entering storm drain inlets and debris is swept up, if necessary. 11. Excess material is not washed from exposed aggregate concrete or similar treatments into an unprotected street or storm drain inlet. An unpaved area is designated for sweeping up and for proper disposal of excess materials. 12. Only as much water as necessary is used for dust control to avoid runoff. 13. As much material as possible is swept up and disposed of properly. Streets are only washed down if runoff is controlled or contained. 14. Drips from parked paving equipment are caught with pans or absorbent material placed under the machines or the area is bermed around them to the maximum extent practicable. 15. All spills and leaks from other equipment and work site areas are cleaned up using dry methods (absorbent materials and/or rags). Absorbent materials and rags are disposed of properly. If spills occur on dirt areas, contaminated soil is dug up and removed properly in a timely manner. MUNI - 5

7 16. During unexpected rains appropriate action is taken to prevent the polluting of stormwater runoff (e.g., runoff diverted around work areas). 17. Spill absorbent materials are stored on vehicles to be used in the event of a spill. 18. Waste materials are contained, swept up and disposed of properly according to their Material Safety Data Sheet. 19. Sprayer paint supply lines are flushed at the corporation yard. Approved collection methods are used and waste materials are disposed of or recycled at an appropriate waste facility. 20. Sprayers and patch paving equipment are cleaned at the end of the day, to the maximum extent practicable. Approved collection methods are used and waste materials are disposed of or recycled at an approved facility. 21. Sprayers, patch and paving equipment are covered to prevent rainfall from contacting pollutants (examples of cover include, but are not limited to, tarps, overhangs or inside of buildings). General BMPs for Municipal Maintenance Facilities All storm drain inlets within the City s wastewater treatment facility, solid waste transfer station, fleet vehicle maintenance facility ( shop ), fertilizer and pesticide storage area, and Sunset Park drain directly to evaporation ponds at the wastewater treatment plant and nothing from these sites is discharged into Marsh Creek. David Mullaney, Wastewater Operations Manager, is assigned the primary responsibility for coordinating the implementation of the BMPs. The City s Public Works Department Safety/Special Projects Coordinator is assigned to assist with the coordination of the BMPs required by the Health Department, in addition to responsibilities associated with operation and maintenance verification activities. Spill kits are made available at the following locations: Herbicide/pesticide storage area Diesel fueling tank Fleet maintenance shop Wastewater treatment plant (lab, chemical feed, on vehicles) Solid waste transfer station and each solid waste vehicle Warehouse The facilities for municipal maintenance are inspected annually. During inspections, locations of spill kits, clean-up equipment and personal protective equipment are verified. As mentioned in the Storm Drainage Facility Inspection & Maintenance section, the Fleet Manager keeps a log of all hazardous waste manifests. The only hazardous material of any appreciable quantity that is stored in the shop is used oil. The used oil is stored in double containment tanks that are picked up by Asbury Environmental Services, Co. on a regular basis (average time is sixty (60) days). Even though the drainage inlets around the shop drain to the percolation ponds in the wastewater facility if there was spill the affected inlets are covered with recyclable absorption mats. The absorption mats are picked up and exchanged for laundered mats by Industrial Laundry Service. The vehicle brake and parts washers and grease sweep are removed, cleaned and returned to the shop on a regular basis by Safety MUNI - 6

8 Clean Company. Non-hazardous cleaning solutions are used. Uniforms and rags are laundered by Mission Uniform Service. Fleet vehicles and equipment, for the most part, are parked within the fenced confines of the corporation yard. Pool vehicles are parked in the municipal lot downtown. Vehicle/equipment washing is done at a commercial car wash facility. On an as needed basis, vehicles/equipment may be washed at the Public Works Facilities; however, all stormwater drains into onsite basins. The corporation yard has one (1) 1,000 gallon red diesel fuel dispensing tank on a concrete apron on the side of the Street Maintenance Division storage building. The City s Fleet Maintenance Division continues to participate in the Contra Costa Health Services, Hazardous Materials Management Program, and submits their annual C.U.P.A reports as required by the program. The City s Fleet Maintenance Division was certified as a Green Business in 2006 and continues to meet the requirements for the program. The certification will expire in 2009 and the Fleet Maintenance Division is in the process of being re-certified with the Bay Area Green Business Program, an arm of the Association of Bay Area Governments. The re-certification process includes a review of environmental and energy conservation practices plus pollution prevention efforts. Everything the Fleet Maintenance Division creates or uses is recycled. The used oil is collected for a recycler. All lubricants and anti-freeze are recycled. The grease rags are laundered or cleaned and reused instead of tossed. An absorbent powder made of cork and absorbent pads that can be cleaned and reused is used for spill cleanup. All solvents are recycled by a company that cleans and recycles them. Lead batteries are recycled. The building facility is energy and water efficient with skylights and low-flow toilets. Staff is very conscious of oil spills that could get into the groundwater. If there is an oil spill on the ground, it is cleaned up immediately with absorbent pads. The City operates a five (5) million gallon per day ( mgd ) wastewater treatment plant under Order No NPDES No. CA The City currently treats an average of 3.2 mgd of wastewater for discharge into Marsh Creek. Currently, this discharge meets and, in some cases, exceeds strict Federal and State water quality standards set forth in the City s National Pollutant Discharge Elimination System Permit ( NPDES ) issued by the California Regional Water Quality Control Board. Additionally, the City s wastewater treatment plant discharges high quality treated wastewater as recycled water, which meets and, in some cases, exceeds State of California Title 22 Drinking Water Standards. The City s Public Works staff does apply herbicides. The City sprays right-of-ways to control weed growth. In general, areas are chemically treated with herbicides, with limited use of herbicides in favor of more management techniques, such as mowing and disking. The greatest portion of herbicide applications in the City are Roundup-Pro and Direx 4L. They are applied to specific targets with little opportunity for runoff. Spraying is performed with dedicated backpacks and dedicated spray rigs. The County inspects MUNI - 7

9 the equipment used for these applications twice a year. Monthly reports are submitted to the County with amounts and types of herbicides used. Herbicide applicators receive annual training administered by a licensed Pest Control Advisor. The training is per U.C. Extension guidelines. The applicators must complete a minimum of twenty (20) hours of rules, laws, and regulation training every two (2) years. Employees are regularly stopped and inspected by U.C. Extension field inspectors and have not received any violations or citations. All employees must go through intensive pesticide/herbicide safety training, including emergency & health training. Records are kept on file in the Public Works Street Maintenance Division office. All used containers are disposed of by following all State and local regulations. Chemicals are stored in a locked room indoors in a specially built containment cage where the only persons having access to the chemicals are licensed applicators. The City is contracted with three (3) landscape maintenance firms to perform maintenance of parks, public spaces and trees. American Civil Constructors, East Bay Construction Company, and Sycamore Landscape Company perform maintenance of our City parks, public streetscapes and open space, while West Coast Arborists performs maintenance of all City-owned trees. In general, although areas are chemically treated with pesticides, we encourage these firms to limit the use of pesticides in favor of more natural vegetative management techniques. The greatest portions of pesticide applications in the City are the herbicide Kleenup Pro, which has the active ingredient of glyphosate. It is applied to specific targets with little opportunity for any kind of runoff. The majority of spray work is performed with dedicated backpacks, so there is no cleaning to switch use to another product. If pressed to evaluate efforts to reduce or eliminate, the City does a very good job keeping pesticides in target areas with little to no contamination of non-target areas. The contractors IPM practices use cultural, mechanical and chemical methods. The cultural practice centers on keeping plants healthy so they can use their own defenses to fight off pests and disease. They use mechanical methods to remove pests or diseased plants as needed. Occasional pest populations requiring treatment are chemically treated with a category 3 non-persistent insecticide. The contracted landscape maintenance firms pesticide applicators receive yearly training administered by a licensed Pest Control Advisor. The training is per U.C. Extension guidelines. The contractors applicators are regularly stopped and inspected by U.C. Extension field inspectors and have not received any citations. The contractors do not use persistent pesticides containing active ingredients such as copper or diazinon. Chemicals are stored in a locked room in the corner of the shop and can only be accessed using an exterior door. The only personnel having a key for the storage room are the applicators. All products are used; there is no disposal except for empty containers. These containers are triple rinsed, punctured and crushed to prevent reuse. MUNI - 8

10 The contractors do their best to keep fertilizer applications to the target landscape. Sidewalks and gutters are cleaned of any fertilizer traces before the crews leave the site. The City does not own or operate a municipal golf course. Modifications: No Performance Standards have been modified or added during the current reporting period. Fiscal Year 2009/2010 Goals: Continuance and refinement of the following milestones/goals of the City s Municipal Maintenance Performance Standard Category cited in the prior year s report provide a positive gauge of our program s effectiveness: Develop/refine implementation strategies to fit the site specific needs, characteristics, and priorities of the City of Brentwood. Establish/refine program priorities on the basis of pollutants of concern, with less emphasis on activity-based prioritization. Complete re-certification of the City s Fleet Maintenance Division as a Green Business by the Bay Area Green Business Program. Continue to emphasize trash reduction efforts in compliance with Provision C.10 of the pending MRP. Following are more specific departmental goals: Litter Removal in Public Spaces During the past year the City opened one (1) new park. The Parks and Recreation Department maintains fifty-four (54) parks. The Parks and Recreation Department provide trash receptacles at each site and all are serviced weekly. If receptacles are filling faster, the park will be scheduled for trash service two or three times a week based on the volume. The Parks and Recreation Department continues to meet the maintenance needs of public areas and monitor/track trash removal to ensure that adequate litter receptacles are distributed and serviced. Solid Waste Transfer Station In a continuing effort to improve the operational efficiency of the City s solid waste transfer station and to update the environmental standards of the facility, City staff has been working on a new design at a new site located just north of the existing facility. The plans will include the operation moving into a building with an above ground loading to accommodate the expected growth to build out of the City ( Attachment MM-3 ). These goals will be modified, as necessary, based upon the requirements of the reissued Municipal Regional Permit. MUNI - 9
