1 ATTACHMENT A SANTA MARGARITA RIVER WATERSHED TRANSPORTATION DEPARTMENT NPDES PROGRAM The s NPDES activities for FY2/3 included the Roadside Litter Removal Program, MS4 Facilities Inspection & Cleaning Program, and the continued development of the GIS database for the MS4 Mapping. The is currently staffed with an NPDES Coordinator; their primary responsibility is to comprehensively administer the s NPDES Program. A staff GIS Analyst has the responsibility to maintain the GIS NPDES databases: Inlets, Outlets, Culverts, Swales, Channels, Basins, and Outfalls with associated annual inspection and cleaning information; the MS4 Permit Manager database; WQMP, Maintenance Yard and Material Site inspections and assessments, and training. ROADSIDE LITTER REMOVAL PROGRAM The Roadside Litter Removal Program has a crew of three (3) employees that provides roadside cleanup efforts. The Litter Crew predominantly picks up roadside blow trash by hand. This effort has proven successful in reducing the amount of debris and anthropogenic litter entering the MS4. The funding for this Program is provided through gas tax revenue. The approximate road miles that were cleaned in the Santa Margarita River Watershed and the approximate tonnage of anthropogenic litter that was removed under this program for this reporting period are listed in the following table: Santa Margarita Watershed Roadside Litter Removal Program (FY2/3) Road Miles 47 miles Anthropogenic Litter 30 tons MS4 FACILITIES INSPECTION AND CLEANING PROGRAM The MS4 Facilities Inspection and Cleaning Program is supported by a crew of three (3)

2 employees ( NPDES Crew ). The funding for this Program is provided by gas tax revenue. The NPDES Crew performs inspection, cleaning and maintenance on all storm drain facilities within the County right-of-way at least once between May and September 30 of each year. The NPDES Crew ensures stencils/curb markers with the message Only Rain Down the Storm Drain are placed and maintained on all inlets as a deterrent to illicit connections and discharges into the MS4 facilities. The approximate tonnage of litter that was removed from the Santa Margarita Watershed under this program for this reporting period is listed in the following table: Santa Margarita River Watershed FY2/3 Assessment of the MS4 Facilities Inspection & Cleaning Program Effectiveness Total Inspections Total Maintenance Anthropogenic Vegetative Sediment Total (%) Effectiveness Inlets % Outlets % Culverts % Swales % Channels % Basins % Total % ROAD REPAIR AND STREET SWEEPING For FY2/3, the received a total of 597 complaint calls countywide for general road repair and maintenance, of which the total number and types of complaints within the Santa Margarita Watershed are shown in the following table: 2

Road sidewalk, curb gutter damage & repair Total 47 Currently, all streets in County Service Area (CSA) 52 are swept. New development projects within the County (with curb and gutter) are required to annex into CSA 52 in order to receive street sweeping services. These services are contracted out and roadways are swept at least once a month. The has increased the frequency of street sweeping to twice a month in problematic areas (e.g., excessive complaints). The approximate curb miles that were swept and approximate tonnage of litter that was removed from street sweeping activities Countywide for this reporting period are listed in the following table: Street Sweeping Countywide (FY2/3) Type of Litter Tonnage Percent Curb Miles Anthropogenic Litter % - Vegetative Litter % - Sediment Litter % - Totals % 3,645 3

4 FISCAL EXPENDITURES Fiscal expenditures for NPDES activities for FY2/3 include: Program Administration (including NPDES Watershed-specific activities), MS4 Mapping, Santa Margarita River Watershed Activity (e.g., catch basin inspection and cleaning), Roadside Litter Removal Program, Street Sweeping CSA52 and Servicing Catch Basin Fossil Filter Inserts. The Overlay, Sealing activity was included since this activity significantly reduces the pollutant loads caused by deteriorating roads. The following table summarizes the NPDES Program expenditures and fund sources: NPDES Program Expenditures Santa Margarita River Watershed NPDES Major Program/Activity Funding Source FY2/3 Expenditures NPDES - Program Administration Gas Tax $85,706 (Project Number Z ) NPDES -Watershed (Project Number Z ) Gas Tax $43,34 MS4 Mapping (Project Number Z ) Santa Margarita River Watershed Activity MS4 Facilities Inspection & Cleaning Program (Project Number Z ) Street Sweeping CSA 52 Gas Tax $00,57 Gas Tax $87,346 County Assessment $382,0 Area 52 L&LMD $5,499 Servicing Catch Basin Fossil Filter Inserts Santa Margarita River Roadside Litter Removal Program Gas Tax $395,408 *Overlay, Sealing Gas Tax $3,345,528 Total $4,645,302 *Not part of the overall NPDES Program; however, considered a significant NPDES-related activity.

The Highway Operations Division provides the County with coverage concerning illegal connections or illegal discharges (IC/ID) within the storm drain systems (inlets, outlets, culverts, swales, channels and 6

7 basins). The District Road Maintenance Supervisors and their staff visually inspect the storm drain infrastructure within their District as part of their daily routine. They specifically focus on problematic areas where IC/ID has repeatedly occurred. The Permit Engineer also mitigate IC/ID issues by sending letters to property owners that encroach upon County right-of-way with illegal connections or other obstructions, and if needed, these cases are reported to Code Enforcement. The Permit Engineer is responsible for reviewing encroachment applications along County roads. If the IC/ID issue is not remedied in a timely manner, it is corrected by the County and billed to the property owner.. 7
