El Polin Springs Restoration Improvements

Stormwater Pollution Prevention Plan Preparation, Monitoring, and Inspection Services

EBA Engineering was obtained by the National Park Service to prepare and monitor construction Storm Water Pollution Prevention Plans (SWPPPs) for the El Polin Springs Restoration Improvements. To assure compliance with the requirements of the 2009-0009-DWQ Construction General Permit, EBA Engineering prepared SWPPPs, Notice of Intents (NOIs), and annual reports as well as provided storm water inspections, monitoring, and sampling during construction.

The SWPPPs included detailed information and procedures that assured storm water quality on each construction site. Such information included project descriptions and construction procedures, site risk assessments, guidelines for the use of Best Management Practices (BMPs), site maps showing BMPs installation and monitoring locations, as well as a Construction Site Monitoring Program (CSMP). A dewatering program was created and implemented as a part of this project.

The SWPPP's were implemented during construction and inspections, monitoring and sampling were performed. Inspections, monitoring, and sampling included weekly site visits, obtaining precipitation event forecasts from the National Weather Service, writing and initiating Rain Event Action Plans (REAPs), and collecting storm water samples according to the CSMP's.
