The LDEQ, Office of Environmental Services, is accepting written comments on a draft modification of a Louisiana Pollutant Discharge Elimination System (LPDES) permit prepared for Targa Midstream Services, LLC, Lowry Gas Plant, 811 Louisiana, Suite 2100, Houston, TX 77002. The facility is located at 810 Lowry Hwy, 1.5 miles south of Lowry on Louisiana Highway 3056, in Cameron Parish.
The principal discharge from this existing source is made into Mermentau River, waters of the state classified for primary contact recreation, secondary contact recreation, and propagation of fish and wildlife. Under the SIC Code 1321, the applicant proposes to discharge reverse osmosis reject water, process and non-process area stormwater, and once through non-contact cooling water from an existing natural gas processing plant.
During the preparation of this permit, it has been determined that the discharge will have no adverse impact on the existing uses of the receiving waterbody. As with any discharge, however, some change in existing water quality may occur.
This permit is being modified to indicate that the collection of Clean Water Act 316(b) cooling water intake structure (CWIS) data will be required only if the facility starts using the intake structure again on a regular basis. See Other Conditions, Paragraph G of the permit. In accordance with LAC 33:IX.3105.B.2, only those permit limitation and conditions pertaining to the draft modifications are open to public comment.
