GEC Dewatering Workshops Available


Temporary dewatering to facilitate construction of a roadway or installation of a buried utility is a common occurrence. For construction projects, permitting for stormwater run-off and groundwater withdrawals due to dewatering (water quantity) is a familiar process; however, the permitting of dewatering effluent discharge (water quality) is still unfamiliar, new territory. The many factors and options involved in dewatering discharge permitting can be overwhelming at first glance. GEC has developed a workshop presentation to provide the community with education regarding the following issues:

 

  • clarification of permitting for dewatering withdrawal versus permitting for dewatering discharge,
  • discussion of discharge options,
  • clarification of the discharge permit requirements, and
  • discussion of allowable deviations to permit requirements.

GEC has trained over 350 people in 2008 to develop cost-effective and timely permitting strategies for dewatering during construction. Permitting of dewatering discharge has received a lot of attention recently due to increased enforcement of the permit requirements by the Florida Department of Environmental Protection (FDEP). In the majority of cases, the dewatering effluent is not contaminated by petroleum products or other hazardous materials, but a dewatering discharge permit is still required. Any non-contaminated dewatering effluent that is going to be discharged to a surface water body requires the "Generic Permit for the Discharge of Produced Groundwater from Any Non-Contaminated Site Activity", dated February 2, 2000 (Chapter 62-621.300(2), FAC). The Generic Permit requirements are fairly easy to satisfy and include sampling and analyzing the groundwater prior to dewatering to verify that it's not contaminated. GEC's workshop addresses the requirements of the permit and clarifies how to feasibly implement the permit requirements based on the constraints of each individual project.
