The State of Hawaii Department of Health (DOH) proposes to issue a Section 401 Water Quality Certification (WQC), which includes conditions and requirements, to the City and County of Honolulu (CCH), Department of Facility Maintenance (DFM), for the Salt Lake Debris Basins Construction Project, which is subject to compliance with requirements authorized under the Clean Water Act (CWA, 33 U.S.C. 1344), Section 404.
The Owner information is as follows:
Owner: City and County of Honolulu (CCH), Department of Facility Maintenance (DFM)
Contact: Mr. Randall R. Wakumoto, Storm Water Quality Branch Head
According to the Application, two (2) grass-lined debris basins will be constructed to intercept and capture rocks, sediment and debris before it enters the City-owned storm drain channel and discharges into Salt Lake. Each basin will be equipped with a 3-foot high concrete slotted weir spillway and a stilling basin comprised of vertical concrete retaining walls on either side of a concrete slab bottom. A new asphalt access road from Likini Street and concrete maintenance ramps that lead down into each basin will also be constructed to provide access for maintenance equipment.
The proposed Salt Lake Debris Basins Construction Project received Nationwide Permit #43, (Stormwater Management Facilities) Verification issued on June 8, 2018, by the U.S. Army Corps of Engineers, Honolulu District which requires that
“… Prior to the initiation of any construction, projects qualifying for this NWP must receive a Section 401 Water Quality Certification (WQC) (or waiver), issued by the State of Hawaii, Department of Health, Clean Water Branch (DOH-CWB).”
The drainage ditch and Salt Lake are classified by the DOH as “Inland Waters, Class 2.”
Based on an evaluation of the Section 401 WQC Application, the supporting information, which are relevant to water quality considerations, and when all requirements and conditions contained in this proposed Section 401 WQC are fully complied with, there is a reasonable assurance that the discharges resulting from the proposed construction activities will be conducted in a manner which will not violate the applicable water quality standards and will comply with the applicable provisions of CWA, Sections 301, 302, 303, 306, and 307.
This proposed Section 401 WQC shall expire two (2) years from the date of issuance or until the applicable WQC are revised or modified, or Department of the Army, Nationwide Permit #43 is modified, revoked, suspended, or expired, or when the project related construction activities are completed, whichever is earlier. If the applicable WQC is revised or modified, before the proposed expiration date, and such that the activity complies with the revisions or modifications to the WQC, this Section 401 WQC shall continue to be valid for the remainder of the two (2) year period.
The Director may, upon receipt of written request from CCH-DFM or its Duly Authorized Representative, administratively extend the expiration date of the issued Section 401 WQC. The request shall be submitted at least thirty (30) calendar days before the Section 401 WQC expires. The decision by the DOH to allow an administrative extension will be made on a case-by-case basis taking into account compliance history and impact to receiving State water quality.
Persons wishing to comment upon or object to the proposed determinations or request a public hearing should submit their comments or request in writing no later than thirty (30) calendar days from the date of this notice either in person or by mail, to:
