As of March 10, 2003, all construction activities that disturb one acre or more of land, or disturb less than one acre — but is part of larger common plan of development — must obtain permit coverage. Permit coverage requirements are individual stormwater permits or coverage under Statewide General Construction Activity Stormwater Permit (GCASP).
Most construction activities fall under GCASP requirements. Construction activities include but are not limited to soil disturbance, clearing, grading, stock piling or excavation. However, an individual permit may be issued at the discretion of the Regional Water Quality Control Board.
On June 18, 2003, the State Water Resources Control Board adopted Stormwater Discharges Associated with Construction Activity from Small Linear Underground/Overhead Projects (Small LUPs). Small LUPs that disturbs at least 1 acre but less than 5 acres of land during construction include but are not limited to:
• Any conveyance, pipe or pipeline for the transportation of any gaseous liquid (including water, wastewater for domestic municipal services), liquescent or slurry substances.
• Any cable line or wire for transmission of electrical energy
• Any cable line or wire for communications (ex. telephone, telegraph, radio or television messages) and,
• Associated ancillary facilities
To apply for permit coverage under GCASP, individual permit or Small LUP, the owner or operator of the construction site is responsible to file:
• Notice of Intent (Page 1 of 13) (NOI) or permit application (page 98 of 104) with the State Water Resources Control Board of the California Environmental Protection Agency prior to commencement of construction activities. Mail a complete NOI package including the original signed NOI, site map and appropriate fee to SWRCB at the following address:
• Develop and implement a Stormwater Pollution Prevention Plan (SWPPP). The plan should include erosion and sediment control and pollution prevention best management practices (BMPs). BMPs are methods to prevent or control stormwater runoff and the discharge of pollutants. The plan requires (1) advance planning and training to ensure implementation of the BMPs, (2) erosion and sediment control BMPs in place until the area is permanently stabilized, (3) pollution prevention BMPs to keep the construction site clean and (4) regular inspection of the construction site to ensure proper installation and maintenance of BMPs.
The SWPPP shall be completed prior to the submittal of the NOI. The SWPPP shall be amended whenever there is a change in design, construction, operation or maintenance which has a significant effect on the potential for discharge of pollutants. The SWPPP shall also be amended if it proves to be ineffective in significantly reducing pollutants from sources identified in the Permit. The SWPPP shall also be amended to indicate any new contractor and or subcontractor that will implement any measure of the SWPPP. All amendments shall be signed, dated and kept as attachments to the original SWPPP.
The contents of the construction SWPPP consists of:
1. Site Evaluation and Design Development
This first step in preparing a SWPPP is to define the characteristics of the site and the type of construction that will occur. This involves collecting site information, identifying natural features that should be protected, developing a site plan design, describing nature of construction activity and preparing pollution.
The second step is to assess the impact of the construction project on stormwater runoff.
3. Control Selection and Plan Design
The third step is to document the procedures to prevent and control polluted stormwater runoff. Site must be designed to infiltrate the stormwater into the ground and keep it out of the storm drains.
4. Certification and Notification
After the SWPPP is developed, the authorized representative must sign and keep the SWPPP on site so the staff can implement SWPPP measures.
5. Implementing and Maintaining Plan
The BMPs must be inspected regularly especially before and after rain events. Many BMPs are designed to handle a limited amount of sediment. If the BMPs are not maintained, the BMPs become ineffective and a source of sediment pollution. It is also important to keep records of BMP installation, implementation and maintenance.
6. Completing the Project: Final Stabilization and Termination of the Permit
Notice of Termination (NOT) is required when:
