Potential and Quantification of Street Sweeping Pollutant Reductions towards addressing TMDL WLAs for MS4 Compliance
Municipal separate storm sewer system (MS4) permittees face costly obligations to reduce pollutant loadings needed to achieve waste load allocations (WLAs) and meet total maximum daily loads (TMDLs). Street sweeping is potentially an effective BMP since streets exist throughout urban watersheds, …

Leveraging Technology to Add Value to a Phase II NPDES Permit
… of small Municipal Separate Storm Sewer Systems (MS4) in the control of runoff from urban areas. The complex task of urban runoff mitigation has been investigated for several decades, resulting in a large variety of available computing and measurement tools for urban stormwater management. …

Evaluating the Effectiveness of Regulatory Stormwater Monitoring Protocols on Groundwater Quality in Urbanized Karst Regions
… data, along with survey data collected from MS4 Phase II communities, and an analysis of current federal, local, and state water quality regulations, to assess the need for karst-specific water quality regulations. Water quality data indicate that significant levels of contamination are …

An Analysis of Trends in U.S. Stormater Utility and Fee Systems
… of SUFs established increased near Phase I MS4 permit and Phase II small MS4 permit deadlines.

Development of Effective Procedures for Illicit Discharge Risk Mapping
… of municipal separate storm sewer systems (MS4s) are required to address illicit discharges as part of the National Pollutant Discharge Elimination System (NPDES) stormwater program. Field reconnaissance is an effective measure to detect and identify illicit discharges, but requires …

Analyses of a genic male-sterile mutant in soybean
… genic male-sterile mutants: ms1, ms2, ms3, ms4, ms5, or ms6. No linkage was detected between the male-sterile gene and flower color (W1 locus), or between the male-sterile gene and pubescence color (T1 locus). Developmental and enzymatic studies showed that sterility was caused by retention …

Multipurpose Approaches to Regional Goals: Chapters in Environmental and Development Economics
… i.e. Municipal Separate Storm Sewer Systems (MS4s), choose from the strategies at their disposal to achieve compliance with their Chesapeake Bay Total Maximum Daily Load (TMDL) obligations. To address declining Chesapeake Bay water quality, the United States Environmental Protection Agency …

Storm Water System Monitoring for the Small Municipality Under Phase II of the National Pollutant Discharge Elimination System
… of municipal separate storm sewer systems (MS4) and on the Texas Pollutant Discharge Elimination System (TPDES) Multi-Sector General Permit (MSGP). The three watersheds were determined to have multiple statistically significant differences for some parameters between their Base Flows and …

Effectiveness of Municipal Collaboration for Watershed Management in the Southern Colorado River Basin
… (NPDES) Municipal Separate Storm Sewer Systems (MS4) permits as issued by the United States Environmental Protection Agency (US EPA). A large body of literature argues for rethinking this scale because this does not match natural watershed boundaries.In this paper, I explore the question: Does …

Tectono-stratigraphic evolution of the offshore Benin Basin, SW Nigeria
… post-rift (late Aptian - latest Maastrichtian), MS4 - transgressive (latest Maastrichtian - middle Miocene) and MS5 - regressive (Middle Miocene - Holocene). Rifting by N-S orientated orthogonal extension took place in the Barremian to late Aptian. This led to the formation of two synchronous …

Sociotechnical systems in campus stormwater management: impediments and driving forces for refined sustainable systems
Throughout the United States, stormwater runoff from streets and similar hardscapes has had detrimental effects, often resulting in flooding, erosion, and health concerns. This thesis focuses on stormwater management as it relates to university campuses and the benefits of having formal stormwater …
