401 Water Quality Certification from the Division for the above referenced project. Additional information
(signature page & agent authorization form) was received on November 9, 2016. A request for additional
information was sent on December 5, 2016. Additional information was received on February 2, 2017. The
Division has determined that the stormwater management plan submitted with your application is
incomplete and cannot be processed. The application is on -hold until all of the following information is
received:
The Stormwater Management Plan (SMP) must be designed in accordance with either the newly
developed Stormwater Design Manual, or with the archived Stormwater BMP manual. Both manuals
are available on the Division of Energy, Mineral and Land Resources website.
a. Both manuals require that sizing of the stormfilter system shall be in conjunction with
upstream closed detention based on designing the system to provide capture and
treatment of 75% of the first 1.0" rainfall. Please provide calculations and plans that clearly
show the water quality design volume.
Please provide specific details regarding the number and configuration of cartridges as well
as calculations to support the design criteria of a maximum media flow rate of 1 gpm. The
current Stormwater Design Manual indicates that this information can be provided by
Contech to the designer.
You must specify the type of media to be used in the cartridges.
2. Please provide a complete supplement form for the Stormfilter system. Please note that the
supplement form includes a "Required Items Checklist" tab. Please ensure that all items noted on this
