Public Notice - Conway WWTP Effluent Structure

October 19, 2020

FINAL PUBLIC NOTICE

Grand Strand Water & Sewer Authority has applied for Federal Emergency Management Agency (FEMA) Hazard Mitigation Grant Program (HMGP) funding through the South Carolina Emergency Management Division (SCEMD).

Funding for the proposed project will be conditional upon compliance with all applicable federal, tribal, state, and local laws, regulations, floodplain standards, permit requirements and conditions.

Applicant: Grand Strand Water & Sewer Authority

Project Title: DR-4394-022, Conway Wastewater Treatment Plant (WWTP) Effluent Structure

Location of Proposed Work:

            Name of Structure: Conway WWTP Effluent Structure   

            Address of Structure: 2915 New Road, Conway, SC 29527

Special Flood Hazard Area Zone:

This project includes the construction of an elevated effluent structure at the Conway WWTP that will serve as a replacement for the existing structure, located in flood zone AE.  Confirmation of location was made by reference to the latest Flood Insurance Rate Map, Panel 45051C0504H. The proposed work will conform to all applicable State of South Carolina and local floodplain regulations. The proposed work will take place on the existing Conway WWTP site and will have no effect on the local floodplain. The flood action will be mitigated by elevating the structure to a height above Hurricane Florence record setting flood levels.

Proposed Work and Purpose:

In an effort to mitigate future flooding and damage to the existing effluent structure at the WWTP, GSWSA would like to construct a new, raised effluent structure (with UV disinfection, aeration system & flow measurement).  This would include a new sewer force main sewer line to pump flows from an existing clarifier to the new raised structure as well as a new outfall line discharging from the new structure. 

Alternatives: 

No other feasible alternatives as we are restricted to the current location of the Conway WWTP.  Relocating the WWTP is not an economically or hydraulically feasible option due to capital costs for upgrading and relocating gravity collection systems, transmission main lines and the actual treatment facility.

Comment Period:

Comments are solicited from the public; local, state or federal agencies; and other interested parties in order to consider and evaluate the impacts of the proposed project. The comments should be made in writing and addressed to Grand Strand Water & Sewer Authority. All comments are due within 30 days of this notice. Grand Strand Water & Sewer Authority will forward comments to applicable regulatory agencies as needed.

Interested persons may submit comments, obtain more detailed information about the proposed action, or request a copy of the findings by contacting:
