ILLICIT DISCHARGE CONTROL ACTIVITIES

QUALITATIVE RESULTS

Municipality: City of Antioch Permit Year: (2008/2009)

Introduction:

The goal of the Illicit Discharge Control Activities (IDCA) program is to prevent or remove contaminants from entering the storm drain system and/or watershed. This is achieved by conducting field investigations; investigating spill reports and complaints; performing clean-up activities as necessary; evaluating source(s) of non-stormwater discharge; and enforcement action. Two (2) Neighborhood Improvement Services (NIS)/Code Enforcement officers and 2 NPDES inspectors are responsible for implementing IDCA performance standards. IDCA is also implemented by public works personnel while in the field. In addition to those employees previously listed, the City has continued its contract with Delta Diablo Sanitation District (DDSD) to perform storm water inspections for target priority businesses. Two (2) DDSD employees perform those inspections. In addition to storm water inspections for target businesses, DDSD inspectors are also trained in IDCA and have authority to issue Notice of Violations (NOVs) on behalf of the City. The primary contact person for permit compliance is Phil Hoffmeister, Administrative Analyst, (925) 779-7035.

Implementation & Evaluation:

The model Illicit Discharge Control Activities (IDCA) Plan continues to be utilized for conducting effective investigations, tracking, and elimination of illicit discharges. High priority areas include: Vehicle repair facilities, restaurants, Somersville Road, Fulton Shipyard Road, Deer Valley Road, East 18th Street, Viera Avenue (at Oakley Road), Canada Valley Road (at Vista Grande Drive), and various portions of Markley Creek, East Antioch Creek, and West Antioch Creek that are accessible by vehicle. Those areas continue to be trouble spots for illegal dumping. Medium priority areas include parks, schools, shopping centers, and open space. Low priority areas include residential neighborhoods. Most high priority areas are inspected once a week by performing drive-by inspections. Medium priority areas are scheduled once a month, and because of the large amount of residential areas, low priority areas are inspected generally while out in the field on other calls. Field screening inspections are performed by Public Works Streets Maintenance Crew and the 2 City of Antioch NPDES inspectors. The number of labor hours needed to perform the field screening is estimated at 340 hours.

Conducting field investigations and performing clean-up activities were most effective in preventing, removing, and/or reducing pollutants from entering the storm water system or watershed. When resolving investigations, violators are educated on proper materials disposal and, when responsible parties can be determined, clean-up orders are given. In some cases, administrative citations are issued.

Spill response calls are generally routed through the NIS Department. Depending on the nature and severity of the call, NIS either responds or forwards those calls to the NPDES inspectors, Public Works Maintenance Department, County HAZMAT, Department of Fish & Game, police and/or fire departments. If an immediate threat to public health is determined, the call is immediately forwarded to 911.

The City of Antioch continues to utilize its administrative citation program. Administrative citation authority has been granted to the Neighborhood Improvement Services/Code Enforcement department, the 2 NPDES inspectors, and the City Attorney. Fines and corrective actions are associated with the citations. The first offense is $100, the second offense of the same ordinance is $250, and $500 for the 3rd offense and each additional offense thereafter. Each citation is considered a separate offense and as such, the fines are compounded. No administrative citations were issued in FY 2008-09.

In 2008-09, field investigators responded to a total of 4 illicit discharge calls. Of those 4 calls:

·  3 were for illicit discharge. These callouts were separate incidents where residents discharged contaminants to the gutter. One was for paint thinner; one for transmission fluid/oil from R.V. repair; and one was sediment from washing off-road motorcycles. Discharge was not directly witnessed; however, evidence of discharge was apparent. Corrective action was to remove material. With the exception of the dirt, no contaminants were observed not to have reached the drain inlet. For all cases, public works crews were dispatched with a vac truck to clean the gutter and drain inlet(s).

·  1 was for a sanitary sewer overflow. This incident was at a private assisted living facility where the sanitary sewer overflowed in the storm drain. Public works crews responded and protected the drain inlets. The blockage was removed by a plumber.

The Household Hazardous Waste (HHW) and curbside used oil-recycling programs continue to be fundamental resources in reducing the amount of potential illicit discharges. This past year, the HHW facility, located at the Delta Diablo Sanitation District, collected an estimated total of 3,763 gallons of motor oil; 11,476 gallons of paint; 1,753 gallons of pesticides; and 22,858 lbs of miscellaneous/non-recyclable wastes. When compared to last year, values for oil, paint, and pesticides represent a combined average increase of approximately 0.5%. The approximately 11% reduction in used oil may be from the promotion and awareness of additional Certified Collection Points (e.g., Kragen Auto Supply). There was a slight decrease of about 2% in the amount of paint disposed; however, pesticide disposal increased approximately 14% and may be attributed to the promotion and increased awareness of the HHW facility. FY 2007-08 was the first year that the HHW facility started collecting electronic

waste (e-waste). For a complete list of e-waste items accepted please see http://ddsd.org/hhw/hazardous_waste.html. No e-waste data was available at the time of writing this report.

Curbside used motor oil collection is performed by the City’s solid waste franchise hauler Allied Waste, Inc. A total of 9,632 gallons of used motor oil were collected by Allied Waste this past year; a 5% increase over last year. The total amount of used motor oil collected from both DDSD HHW facility and Allied Waste combined was 13,395 gallons.

The City continues to implement 2 proactive programs. In November, 2005 the City launched a new residential recycling program. Prior to the new program, residents placed recycling at the curb on service days in open bins, bags, and boxes. On windy days, this resulted in paper, plastic bottles, and other recyclables blowing out and becoming litter. Residents now put all their recyclables in a wheeled cart with a closed lid. This appears to have a positive impact and has decreased street litter on garbage service days. The City has also continued the enforcement of mandatory garbage service requirement of the municipal code. At the time of preparing this annual report, the total numbers of enforcement letters, reinstated service, verified vacancies, and issued citations for non-garbage service were not available. The efforts of this program result in an overall decrease in the number or households without service and the amount of illegal dumping and litter that occurs throughout the City of Antioch.

In March 2007, an internal City employee committee was convened to further address illegal dumping. The committee consists of the Public Works Director; Building and Grounds Superintendent; Streets Superintendent; NPDES Compliance Coordinator; and Solid Waste Compliance Coordinator. The primary goal of the committee is to pool resources to address illegal dumping in the City. The committee meets on a quarterly basis.

Modifications:

Based on the effectiveness of the IDCA PSs, no modifications appear necessary at this time.

Fiscal Year 2009/2010 Goals:

Goals for 2009-10 include:

·  Continue to utilize the administrative fine system,

·  Continue to utilize GIS and other electronic systems for improved tracking of problem areas,

·  Modify, if needed, frequency for repeat inspections of medium and low priority areas,

·  Continue enforcement of mandatory garbage service,

·  Continue the illegal dumping committee and formulate long-term strategies and partnerships.
