Shallow marsh definition

Shallow marsh means a zone within a stormwater extended detention basin that exists from the surface of the normal pool to a depth of six to 18 inches, and has a large surface area and, therefore, requires a reliable source of baseflow, groundwater supply, or a sizeable drainage area to maintain the desired water surface elevations to support emergent vegetation.

Shallow marsh means a zone within a stormwater extended detention basin that exists 1999 from the surface of the normal pool to a depth of six to 18 inches, and has a large surface area 2000 and, therefore, requires a reliable source of baseflow, groundwater supply, or a sizeable 2001 drainage area, to maintain the desired water surface elevations to support emergent vegetation. 2002 "Stormwater detention basin" or "detention basin" means a stormwater management facility 2003 that temporarily impounds runoff and discharges it through a hydraulic outlet structure to a 2004 downstream conveyance system. While a certain amount of outflow may also occur via 2005 infiltration through the surrounding soil, such amounts are negligible when compared to the 2006 outlet structure discharge rates and are, therefore, not considered in the facility's design. Since 2007 a detention facility impounds runoff only temporarily, it is normally dry during nonrainfall periods. 2008 "Stormwater extended detention basin" or "extended detention basin" means a stormwater 2009 management facility that temporarily impounds runoff and discharges it through a hydraulic 2010 outlet structure over a specified period of time to a downstream conveyance system for the 2011 purpose of water quality enhancement or stream channel erosion control. While a certain 2012 amount of outflow may also occur via infiltration through the surrounding soil, such amounts are 2013 negligible when compared to the outlet structure discharge rates and, therefore, are not 2014 considered in the facility's design. Since an extended detention basin impounds runoff only 2015 temporarily, it is normally dry during nonrainfall periods. 2016 "Stormwater extended detention basin-enhanced" or "extended detention basin-enhanced" 2017 means an extended detention basin modified to increase pollutant removal by providing a 2018 shallow marsh in the lower stage of the basin. 2019 "Stormwater retention basin" or "retention basin" means a stormwater management facility 2020 that includes a permanent impoundment, or normal pool of water, for the purpose of enhancing 2021 water quality and, therefore, is normally wet, even during nonrainfall periods. Storm runoff 2022 inflows may be temporarily stored above this permanent impoundment for the purpose of 2023 reducing flooding, or stream channel erosion. 2024 "Stormwater retention basin I" or "retention basin I" means a retention basin with the volume 2025 of the permanent pool equal to three...

  • Total resource cost test or "TRC test" means a standard that is met if, for an investment in energy efficiency or demand-response measures, the benefit-cost ratio is greater than one. The benefit-cost ratio is the ratio of the net present value of the total benefits of the program to the net present value of the total costs as calculated over the lifetime of the measures. A total resource cost test compares the sum of avoided electric utility costs, representing the benefits that accrue to the system and the participant in the delivery of those efficiency measures, as well as other quantifiable societal benefits, including avoided natural gas utility costs, to the sum of all incremental costs of end-use measures that are implemented due to the program (including both utility and participant contributions), plus costs to administer, deliver, and evaluate each demand-side program, to quantify the net savings obtained by substituting the demand-side program for supply resources. In calculating avoided costs of power and energy that an electric utility would otherwise have had to acquire, reasonable estimates shall be included of financial costs likely to be imposed by future regulations and legislation on emissions of greenhouse gases.
