Advanced Drainage Systems, BaySaver Technologies BaySaver BayFilter with Enhanced Media Cartridge (EMC) is an engineered filtration system designed to filter pollutants from stormwater runoff. It is classified as a manufactured treatment device (mtd).
This page provides information on pollutant removal credits for BaySaver BayFilter with Enhanced Media Cartridge, links to supporting information, and links to information on system design, inspection, operation, and maintenance.
When conditions described in this section are met, applicable BaySaver BayFilter with Enhanced Media Cartridge systems are approved for the following removals for total suspended solids (TSS) and total phosphorus (TP).
For more information on credits, see TP and TSS credits and guidance for manufactured treatment devices (mtds)
For a discussion of BaySaver BayFilter configurations see appropriate configurations in the Design Manual.
To receive the full credit, BaySaver BayFilter systems must comply with the following conditions.
Credits apply only to the water being treated by a device. The applicable treatment volume must be determined using one of the methods described here.
The Tier 1 credit equals the TAPE-approved credits. Tier 2 credit was determined by analyzing water quality data collected
MPCA compiled data from the General Use Level Designation Technical Evaluation Report (2019, revised 2023). Summary statistics for the device are shown below.
TAPE means and medians represent values meeting TAPE criteria for TP (inflow concentrations of 0.1 to 0.5 mg/L) and TSS (inflow concentrations greater than 20 mg/L). Of the 22 samples, TAPE medians and means represent 11 samples for TP and 12 samples for TSS.
Meet the conditions specified for the appropriate TP and/or TSS credit. Meet the following conditions, unless conditions for the appropriate TP and/or TSS credit are more stringent.
