Storm Water Pollution Prevention Plan

Farmer Environmental Group staffs a team of Professional Engineers and environmental specialists with extensive experience in preparing and assisting with the implementation of SWP3 for a wide range of industrial facilities and construction projects.  SWP3 are site-specific documents that: 1) identify potential sources of storm water pollution on a specific industrial, municipal, and/or construction site; 2) describe storm water control measures and best management practices (BMPs) that will be used to reduce or eliminate pollutants in Storm Water discharges from the site; and 3) identify the processes the operator of the site will implement to comply with the terms and conditions of the site-specific general permit.  Specific SWP3 requirements are variable in some states and municipalities.  However, most states have adopted the federal SWP3 requirements.  Farmer Environmental Group SWP3 are compliant with federal and local requirements when applicable.

SWP3 regulations are associated with the National Pollutant Discharge Elimination System (NPDES) Storm Water Program which regulates Storm Water discharges from three potential sources: municipal separate storm sewer systems (MS4s), construction projects, and industrial facilities. Most storm water discharges are considered point sources, and operators of these sources may be required to receive an NPDES permit before they can discharge. This permitting instrument is designed to prevent storm water runoff from washing detrimental pollutants into local surface waters such as rivers, water bodies, or coastal waters.

The NPDES Storm Water Program covers the following types of storm water discharges:

    • MS4s – Operators of large, medium and regulated small MS4s may be required to obtain authorization to discharge storm water.
    • Construction Projects – Operators of construction sites that are one acre or larger (including smaller sites that are part of a larger common plan of development) may be required to obtain authorization to discharge storm water under an NPDES construction storm water permit. Where EPA is the permitting authority, operators must meet the requirements of the United State Environmental Protection Agency’s (EPA) Construction General Permit (CGP).
    • Industrial Facilities – Industrial sectors may require authorization under an NPDES industrial storm water permit for storm water discharges. Where EPA is the permitting authority, operators must meet the requirements of EPA’s Multi-Sector General Permit (MSGP).

Our Qualified Staff Can Help Every Step of the Way

SWP3 can be constantly changing documents during the course of a construction project and require evolving compliance measures and applicable notifications by site operators.  In order for a for a site to remain in compliance with the NPDES permitting program, SWP3 or a Storm Water Management Plan (SMP), which details the site’s storm water management initiatives, must be prepared and maintained throughout the entire construction project. As the project progresses and goes through changes, the SWP3 or SMP is required to be revised to incorporate those changes. Farmer Environmental Group personnel are experienced with the current NPDES Storm Water Program, review local and regional SWP3 requirements prior to the issuance of any SWP3, and constantly monitor regulatory actions which may alter SWP3 requirements in order to ensure our clients compliance with applicable regulations.
