Evaluation of stormwater BMPs for implementing industrial stormwater permitting strategy
This study assesses the performance of stormwater best management practices (BMPs) in industrial sectors and their effluent quality to facilitate the development of technology-based numerical effluent criteria. Generally, retention ponds outperform other BMP types for reducing total suspended solids, and media filter and wetland basins outperform other BMPs for metal removal. Detention basins ...

Collaboration as process: a case study of Michigan's watershed permit
Collaborative watershed management has been heavily promoted and widely implemented to address a variety of natural resource concerns, resulting in the adoption and adaptation of the approach to management by regulatory agencies. Although several characteristics or indicators of success for watershed partnerships have been identified in the literature, these often portray a direct cause and ...

Stormwater Management Program Long-Term Effectiveness Monitoring: Can I Reduce Sampling Frequency and Still Detect Trends to Determine BMP Effectiveness
INTRODUCTION Stormwater program managers are challenged with meeting regulatory monitoring requirements to identify long-term trends and the effectiveness of the implementation of Best Management Practices (BMPs) and meeting multiple program requirements with finite resources. This paper provides stormwater managers with methods and several real-world scenarios using 10 years of data from the ...

Airport deicing effluent treatment and regulatory guidelines
Airport and airplane deicing is employed with the use of brines, salts, alcohols or glycols to remove and prevent or delay the formation of snow and ice. In the United States (US), the Federal Aviation Administration requires airlines that operate during icy conditions to perform deicing and anti-icing of aircraft and airfield pavement (USEPA 2011a). These deicing operations use large amounts ...

Stormwater Solids Reduction for NPDES Permits
Finally obtaining a National Pollution Discharge Elimination System (NPDES) Permit is often a relief but is by far not the end of the story. Meeting the requirements of that permit often proves to be quite difficult and stiff fines are freely doled out to those who fail to meet regulatory limits. For one Midwest jet propulsion manufacturing facility, the issue of total daily solids discharge ...

TMDL support activities for the Anacostia river case study
States and EPA are required to establish Total Maximum Daily Loads (TMDLs) for waterways that fail to support their designated uses (e.g., swimming, recreation, aesthetic enjoyment, etc.) under the Clean Water Act. These TMDLs typically establish strict pollutant load limits for municipalities, industries, and other sources such as agriculture. Problem TMDLs can be challenging and controversial, ...

What is stormwater?
Stormwater runoff, water that isn’t absorbed into the ground after a weather event, is a potential water source that cities across the world have struggled with for decades. Why is coping with it such a challenge? Whether the precipitation is water or ice, its addition to the environment can be a problem, especially when a lot of it falls in a short amount of time. When this occurs in ...

Reuse turns stormwater runoff from a problem to an asset
With so much concern about water scarcity around the world, it seems a no-brainer that rain is a good thing. But nothing’s perfect. Even something as beneficial as precipitation can have its downsides. One problem, of course, is flooding. Another problem you may not have thought of comes with stormwater runoff in urban settings. What’s the problem? In cities, buildings and pavement ...

Erosion and Sediment Control: Navigating NPDES Regulations, the SWPPP, and Techniques for Compliance
Erosion and Sedimentation: Why Are They a Problem? The US Environmental Protection Agency lists sediment as the single most common pollutant in rivers, streams, lakes, and reservoirs. With all the potentially harmful chemicals and substances in the world, it seems odd to many people that sediment—dirt, essentially—is singled out as the major culprit. Yet these particles of sand, ...

Integrated Environmental Risk Management in Real Estate Transactions
Traditional risk management posits a rational, five-step process for managing risks. The outstanding differences between this traditional process and the environmental risk management process lie in the technicality and complexity of step one (identifying and analyzing environmental risk) and of the first part of step two (examining the feasibility of alternative risk management, specifically ...
