The update history of SWMM 5 from the original SWMM 5.0.001 to the current version SWMM 5.2.3 can be found at the EPA website. SWMM 5 was approved FEMA Model Approval Page in May 2005, [ 16 ] with a note about the versions that are approved on the FEMA Approval Page SWMM 5 Version 5.0.005 (May 2005) and up for NFIP modeling.
Title 40 is a part of the United States Code of Federal Regulations.Title 40 arranges mainly environmental regulations that were promulgated by the US Environmental Protection Agency (EPA), based on the provisions of United States laws (statutes of the U.S. Federal Code).
The SWMM (Storm Water Management Model), the HSPF (Hydrological Simulation Program – FORTRAN) and other modern American derivatives are successors to this early work. In Europe a favoured comprehensive model is the Système Hydrologique Européen (SHE), [ 11 ] [ 12 ] which has been succeeded by MIKE SHE and SHETRAN .
The CompTox Chemicals Dashboard is a freely accessible online database created and maintained by the U.S. Environmental Protection Agency (EPA). The database provides access to multiple types of data including physicochemical properties, environmental fate and transport, exposure, usage, in vivo toxicity, and in vitro bioassay.
EPANET (Environmental Protection Agency Network Evaluation Tool) is a public domain, water distribution system modeling software package developed by the United States Environmental Protection Agency's (EPA) Water Supply and Water Resources Division.
The 1987 CWA amendments established a non-regulatory program at EPA for nonpoint source pollution management consisting of research and demonstration projects. [28] Related programs, such as the Environmental Quality Incentives Program are conducted by the Natural Resources Conservation Service (NRCS) in the U.S. Department of Agriculture .
It is open-source software and is a widely used, EPA accepted model. [5] DSI continues to develop EFDC using the name EFDC+. Enhancements include adding multithreading capability and more recently full parallel computing with MPI (Message Passing Interface). EFDC+ Explorer is part of the EE Modeling System (EEMS) which includes EFDC+, the ...
EPA has published many methods in its regulations, [4] and has approved the use of other methods published by peer-reviewed sources, such as Standard Methods. [5] Although the effluent limitations are based on the performance of control and treatment technologies (and not the impacts to receiving waters), the regulations do not require ...
