Public Announcements




The Residuals Committee of the Connecticut Section of the American Water Works Association (CTAWWA) wants to inform CTAWWA members about the new general permits issued by the Connecticut Department of Energy and Environmental Protection (DEEP), that will affect all water utilities that discharge water treatment wastewater to the sewer, surface water or groundwater.  Water utilities will have to act quickly to register for the new general permits. On March 30, 2018 the General Permit for the Discharge of Water Treatment Wastewater (WTW GP) will be replaced by the General Permit for Miscellaneous Discharges of Sewer Compatible Wastewater (MISC GP) and the Comprehensive General Permit for Discharges to Surface Water and Groundwater (Comprehensive GP).  The Residuals Committee of CTAWWA has been negotiating with DEEP about the changes to the general permits for the past several years and is trying to help the water utilities comply with the new general permits.  The WTW GP was originally scheduled to expire on March 29, 2015.  This expiration date was extended to March 29, 2018, in response to DEEP’s changes to its general permit program for water treatment wastewaters. 

On October 25, 2013, DEEP issued the MISC GP, which was modified on August 9, 2017, will become effective on March 30, 2018 for water utilities that currently have a WTW GP, and is scheduled to expire on October 30, 2018. The MISC GP groups together all discharges to sanitary sewer systems for regulation, including water treatment wastewater previously regulated under the WTW GP.  The MISC GP will apply to existing permitted water treatment wastewater discharges to sewer systems when the WTW GP expires on March 29, 2018.  Therefore, at the expiration of the WTW GP that allows discharges to the sanitary sewer, water treatment facilities will need to register the sanitary sewer portion of their facility discharges under the MISC GP prior to March 29, 2018.  No registration under the MISC GP is required if total maximum daily flows for all water treatment wastewater discharges to a sanitary sewer from a single facility are less than 1,000 gallons per day (gpd).

On December 14, 2017, DEEP issued the Comprehensive General Permit for Discharges to Surface Water and Groundwater (Comprehensive GP), which will replace the WTW GP (in conjunction with the MISC GP).  The Comprehensive GP will become effective on March 30, 2018 after the WTW GP expires, and is scheduled to expire on March 29, 2023.  The Comprehensive GP consolidates multiple general permits that regulated wastewater discharges to surface water and groundwater.  Water treatment wastewaters discharged to surface waters or groundwaters will need to be registered under the Comprehensive GP. Facilities with existing authorization under the WTW GP must register under the Comprehensive GP within 90 days of the effective date of the Comprehensive GP, or prior to June 28, 2018.

In addition, a presentation on these general permits will be made on February 27, 2018 at the CTAWWA Annual Technical Conference and Vendor Exposition (ATCAVE) at the Radisson, 100 Berlin Road Cromwell, CT.
