Regulatory Division

SUBJECT: Project Number SWF-2016-00086, Transfer Lift Station & Force Main

Mr. Charles Leist City of Waco P.O. Box 2570 Waco, Texas 76702

Dear Mr. Leist:

This letter is in regard to information received November 16, 2017, and subsequent submittals received December 21, 2017, January 4, 2018, and January 15, 2018, concerning a proposal by the City of Waco to construct a transfer lift station and force main in the city of Waco, McLennan County, Texas. This project has been assigned Project Number SWF-2016- 00086. Please include this number in all future correspondence concerning this project.

Under Section 404 of the Clean Water Act the U.S. Army Corps of Engineers (USACE) regulates the discharge of dredged and fill material into waters of the United States, including wetlands. USACE responsibility under Section 10 of the Rivers and Harbors Act of 1899 is to regulate any work in, or affecting, navigable waters of the United States. Based on the description of the proposed work, and other information available to us, we have determined this project will involve activities subject to the requirements of Section 404 and Section 10.

We have reviewed this project under the pre-construction notification procedures of Nationwide Permit General Condition 32 (Federal Register, Vol. 82, No. 4, Friday, January 9, 2017). We have determined the discharge of dredged or fill materials into waters of the United States associated with this project appears to qualify for Nationwide Permit 12 for Utility Line Activities. To use this permit, the permittee must ensure the work is in compliance with the specifications and conditions listed on the enclosures and the special conditions listed below. Additionally, all activities must comply with the water quality certification conditions of the Texas Commission on Environmental Quality (TCEQ) located at http://www.swf.usace.army.mil/Portals /47/Users/053/21/821/NWP%20201 7%20Texas%20401 cert.pdf.

The special conditions are as follows:

1. The permittee shall use a phased cofferdam system for the crossing of the Brazos River as depicted on the “Inverted Siphon Plan & Profile Sheet I of 2” received via electronic mail January 15, 2018, prepared by Lockwood, Andrews & Newman, Inc. The phased cofferdam system shall be used to maintain low flows of the Brazos River.

2. The permittee understands and agrees that, if future operations by the United States require the removal, relocation, or other alteration, of the structure or work herein authorized, or if, in the opinion of the Secretary of the Army or his authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters, the permittee will be required, upon due notice from the Corps of Engineers, to remove, relocate, or alter the structural work or obstructions caused thereby, without expense to the United States. No claim shall be made against the United States on account of any such removal or alteration.

Failure to comply with these specifications and conditions invalidates the authorization and may result in a violation.

Our verification for the construction of this activity under this nationwide permit is valid until March 18, 2022, unless prior to that date the nationwide permit is suspended, revoked, or modified such that the activity would no longer comply with the terms and conditions of the nationwide permit on a regional or national basis. The USACE will issue a public notice announcing the changes when they occur. Furthermore, activities that have commenced, or are under contract to commence, in reliance on a nationwide permit will remain authorized provided the activity is completed within 12 months of the date of the nationwide permit’s expiration, modification, or revocation, unless discretionary authority has been exercised on a case-by- case basis to modify, suspend, or revoke the authorization in accordance with 33 CFR 330.4(e) and 33 CFR 330.5(c) or (d).

The USACE based this decision on a preliminary jurisdictional determination (PJD) that there are waters of the United States on the project site. A PJD is not appealable. At any time you have the right to request and obtain an Approved Jurisdictional Determination (AJD), which can be appealed. If it is your intent to request an AJD, do not begin work until one is obtained.

Our review of this project also addressed its effects on threatened and endangered species. Based on the information provided, we have determined this project will not affect any species listed as threatened or endangered by the U.S. Fish and Wildlife Service within our permit area. However, please note you are responsible for meeting the requirements of General Condition 18 on endangered species.

The permittee must sign and submit to us the enclosed certification that the work, including any proposed mitigation, was completed in compliance with the nationwide permit. The permittee should submit the certification within 30 days of the completion of work.

This permit should not be considered as an approval of the design features of any activity authorized or an implication that such construction is considered adequate for the purpose intended. It does not authorize any damage to private property, invasion of property rights, or any infringement of federal, state, or local laws or regulations.

Thank you for your interest in our nation’s water resources. If you have any questions concerning our regulatory program, please refer to our website at
