Water Quality Certification
Dear colonel Halzwarth:
Pursuant to Section 401 of the Federal Clean Water Act, the State of Georgia issues this certification to 0. s. Army Corps of Engineers, an applicant for a Federal permit or license to conduct an activity in, on or adjacent to the waters of the State of Georgia.
The State of Georgia certifies that there is no applicable provision of Section 301; no limitation under Section 302; no standard under Section 306; and no standard under Section 307, for the applicant's activity. The State of Georgia further certifies that the applicant's activity will comply with all applicable provisions of Section 303.
This certification contingent upon the following conditions: 1. All work performed during construction will be done in a
so as not to violate applicable water quality standards. No oils, grease, materials or other pollutants will be discharged from the construction activities which reach
public waters. 3. No dredging will be conducted during the striped bass
spawning period from March 16 to May 31 of each year. 4. Before any dredging can be conducted during the period
July 1 to September 30, the applicant must secure approval from the Environmental Protection Division of a plan for monitoring of dissolved oxygen in the vicinity
of the dredging site. The plan must include provisions for suspension of dredging during any periods when D.o. values drop below 3.0 mg/1. Results of this monitoring must be submitted to the Georgia Environmental Protection Division, the Georgia Game and Fish Division, and the Georgia Coastal Resources Division within 30 days of the completion of each dredging operation. If the applicant does not maintain a satisfactory record of compliance with this condition, the Environmental Protection Division may prohibit all dredging during the period July
i to September 30 upon written notice to the applicant. 5. Hopper dredging should be conducted during December
through March. These are the times when sea turtles are least abundant in the area of the Savannah ship Channel. Dredging should not be conducted outside these months without implementation of a conservation plan approved by Georgia Department of Natural Resources. This plan should include trawling to remove turtles from the path of the
dredge. 6. The Georgia Department of Natural Resources recommends
that a systematic trawl survey of the Savannah Channel be conducted to confirm the distribution and abundance of turtles in the channel in winter. Data from this survey is to be used to better delineate the times when dredging
is least likely to impact sea turtles. 7. During December through March, dredge and support vessel
speeds should be limited to less than 5 knots during nighttime operations. A trained whale observer should be on watch during daylight hours. If daily aerial surveys
conducted for right whales, the nighttime vessel speed limitation would only need to be enforced when a whale, was spotted within 15 miles of the project area
during the previous daily survey. 8. The removal of the tide gate in the Savannah Back River
and the back fill of New Cut as proposed in the Joint Public Notice dated June 26, 1991 will be conducted prior to or concurrently with the deepening of the Savannah River Harbor Channel as proposed in the Joint Public
Notice of April 19, 1991. It is your responsibility to submit this certification to the appropriate Federal agency.
