"Issuance of the Multi-Sector General Permit for Stormwater Discharges Associated with Industrial Activity, Pursuant to the National Pollution Elimination System"--Page [2]. [Consultation Tracking number: FPR-2014-9094]. [doi:10.7289/V5D798G7 (https://doi.org/10.7289/V5D798G7)].

Industrial stormwater is derived from precipitation and/or runoff that comes in contact with industrial manufacturing, processing, storage, or material overburden and then runs offsite and enters drainage systems or receiving waters. In 1987, Congress significantly expanded the National Pollutant Discharge Elimination System (NPDES) program through amendments to the Clean Water Act to include industrial stormwater runoff conveyed through outfalls directly to receiving waters or indirectly through municipal separate storm sewer systems. The added regulation of stormwater in the NPDES program has been challenging. Stormwater is produced throughout a developed landscape, and its production and delivery are episodic. In 2009, the National Research Council released a comprehensive report on the Environmental Protection Agency's Stormwater Program that covered all sectors of the program. This study builds on that report, with a focus on industrial stormwater monitoring and management.

The NPDES Storm Water Sampling Guidance Document provides a comprehensive description of basic sampling requirements for NPDES storm water discharge permit applications and offers procedural guidance on how to conduct sampling. Many of the procedures in this manual are also applicable to the sampling requirements contained in NPDES storm water permits. Topics covered include background information and a summary of permit application requirements, the fundamentals of sampling (including obtaining flow data, handling samples, and sending them to the lab), analytical considerations, regulatory flexibility regarding storm water sampling, and health and safety considerations. This book will be a cornerstone of NPDES compliance for wastewater treatment plant managers and supervisors, consultants, laboratories, lab managers and chemists, regulators, current NPDES permit holders, and anyone applying for an NPDES permit.

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

This guide shows you how to develop and implement a Storm Water Pollution Prevention Plan specifically designed for your construction site. It should answer any questions you have regarding the NPDES General Permit for Storm Water Discharges from Construction Activities that are classified as "Associated with Industrial Activity" (referred to as EPA's Baseline Construction General Permit). Step-by-step guidelines and checklists walk you through the process of setting up your plan, which makes the book invaluable for consultants, regulators, and construction managers and engineers.
