Reference: Request for Waiver for Monitoring of Certain Conventional Parameters
Submitted with Application for
National Pollutant Discharge Elimination System (NPDES) Permit for Construction and
Construction Dewatering
Camden Exchange
1600& 1614 Camden Road and 109 & 115 West Park Avenue
Charlotte, North Carolina
ECS Project No. 13075-B
Dear Mr. Denard:
ECS Southeast, LLP (ECS) requests on behalf of its client Catalyst Capital Partners that certain
conventional parameters not be required for the proposed discharge as shown in NPDES Permit
Application Form 2C. Specifically, it is requested that monitoring for Biological Oxygen Demand,
Chemical Oxygen Demand, Total Organic Carbon, Ammonia, Temperature (winter), and Temperature
(summer) not be required as part of the permit.
As described in the application package the discharge is for construction dewatering and the
aforementioned parameters are not applicable for the indicated discharge. Summary data tables and
laboratory results are included in the application package for groundwater monitoring that has been
performed at the site.
If you have any questions or comments concerning this waiver request or other related topics, please feel
free to contact us.
Respectfully submitted,
ECS SOUTHEAST, LLP
