SWPPP Compliance Monitoring

North Richland Storm Drainage Outfall Project, Ceres, California

Project Name: North Richland Storm Drainage Outfall Project, Ceres, California
Services: Stormwater Pollution Prevention Plan Preparation
Client: City of Ceres, Public Works Department

The Project Site consisted of an approximate 10-acre parcel of land that the City proposes to develop as a park/recreation facility, consistent with the City General Plan. The Park will consist of soccer fields, a basketball court, shade structures, benches, restroom facilities, two playground areas, picnic areas and a parking lot. Additionally, the City has identified the need for a storm drain outfall to carry water from the park site and adjacent neighborhoods to the Tuolumne River. The proposed storm water drainage basin would collect storm water and carry it to the Tuolumne River via a storm drain pipeline system. Padre completed a Storm Water Pollution Prevention Plan (SWPPP) for the North Richland Storm Drainage Outfall Project, located at the southwest intersection of River Road and Peter John Way, Ceres, Stanislaus County, California. The SWPPP was based on the requirements of the California State Water Resources Control Board (SWRCB), Water Quality Order No. 2009-0009-DWQ, National Pollutant Discharge Elimination System (NPDES) General Permit No. CAS000002 for discharges of storm water runoff associated with construction activity.

Guadalupe Restoration Project – Stormwater Pollution Management, San Luis Obispo and Santa Barbara Counties, California

Project Name: Guadalupe Restoration Project – Stormwater Pollution Management, San Luis Obispo and Santa Barbara Counties, California
Services: Stormwater Pollution Prevention Plan Preparation and Monitoring
Client: Chevron Environmental Management Company

As part of a larger environmental and geoenvironmental scope of services, Padre’s Qualified Storm Water Pollution Prevention Plan (SWPPP) Designer (QSD) prepared a SWPPP for the Guadalupe Restoration Project (Project Site) in accordance with the California Construction General Permit Order No. 2009-0009-DWQ (CGP). The subject Project Site occupies over 2,700 acres of the larger Guadalupe-Nipomo Dunes Complex, and is located on the Central California Coast in San Luis Obispo and Santa Barbara Counties. Project Site activities involve remediation of specified areas of petroleum hydrocarbon-impacted soil as required in Cleanup or Abatement Order issued by the RWQCB in 1998.

This SWPPP utilized a Risk-Based Permitting Approach under the General Permit as set forth by the State Water Resources Control Board (SWRCB) and Regional Water Quality Control Board (RWQCB). The SWPPP detailed sources of sediment and pollutants from the Project Site which could impact storm water discharges, described techniques for minimizing transport of sediment and other pollutants from the Project Site, described best management techniques, and included a sampling and analysis plan, for use in the event that sampling of storm water be deemed necessary.

Padre is responsible for the overall appropriate implementation of the SWPPP at the Project Site. This includes ensuring that project personnel are trained on the following topics:

  • Erosion Control BMPs;
  • Sediment Control BMPs;
  • Non-Storm Water BMPs;
  • Waste Management and Materials Pollution Control BMPs; and,
  • Emergency Procedures specific to the construction site storm water management.

Padre conducts weekly stormwater inspections, provides oversight of best management practices installation and maintenance, and prepares Annual Reports for CEMC for electronic submittal to the RWQCB via the Storm Water Multiple Application and Report Tracking System (SMARTS).

Camp Roberts Photovoltaic Solar Power Plant Project, San Luis Obispo and Monterey Counties, California

Project Name: Camp Roberts Photovoltaic Solar Power Plant Project, San Luis Obispo and Monterey Counties, California
Services: Stormwater Pollution Prevention Plan Implementation Monitoring
Client: Belectric North America

The Project Site consisted of a utility-scale photovoltaic solar power plant on an approximate 7.26-acre area located on the eastern portion of the Camp Roberts, California National Guard Base. Construction of the solar plant included the installation of 52 photovoltaic sub-arrays and one pad-mounted inverter / transformer. Additionally, an electrical interconnection to the Camp Roberts base was created using existing overhead electrical feeders. The project qualified as a Risk Level 2 discharger.

Construction activities included the placement of erosion and sediment control measures, construction of a perimeter chain-link fence and concrete equipment pad, improvement of existing site roads, installation of solar power-generating modules and associated structures, and trenching of electrical conduits. Padre personnel were responsible for the inspection of these construction areas to ensure compliance with the California General Construction Permit order number 2010-0014-DWQ. This included ensuring that storm water discharges to the Salinas River, from storm water retention basins constructed for the project activities, were within state-mandated tolerances. Additionally, Padre personnel inspected weekly the condition of site erosion control measures which included silt fencing, fiber rolls, sandbag barriers, biofilter bags, and compost socks and berms.
