WATER POLLUTION CONTROL PERMIT
DOCKET NO. HI 0000604
March 25, 2020
The Department of Health (DOH) proposes to modify the Waiau Generating Station, HI 0000604, National Pollutant Discharge Elimination System (NPDES) permit to discharge to receiving State Waters.
This permit, issued to Hawaiian Electric Company, is being modified under allowance by Hawaii Administrative Rules (HAR) Section 11-55-16 and Title 40 Code of Federal Regulations (40 CFR), Section 122.62(a)(2). The proposed major modifications include: 1) Allowing the discharge of condensate water associated with the six turbine generators (low volume wastes) from Outfall Serial Nos. 002, 003 and 004; 2) Addition of internal outfall limitations and monitoring requirements for the discharge of the condensate water; 3) Revision of submittal requirements to require the submittal of updated information, including an updated/revised Effluent Monitoring Program; and 4) Clarification of the expiration date.
The expiration of the permit shall remain as August 31, 2024.
In accordance with 40 CFR Sections 124.5(c)(2) and 122.62, only the conditions outlined above shall be reopened. All other conditions shall remain in effect for the duration of the permit. Please note that you may only comment or request a public hearing on the modified/reopened items described above.
Persons wishing to comment upon or object to the draft modified NPDES permit or to request a public hearing, should submit their comments or requests in writing no later than 30 calendar days after the date of this notice, either through e-mail at: cleanwaterbranch@doh.hawaii.gov or by mail at 2827 Waimano Home Road, Room 225, Pearl City, Hawaii 96782.
Copies of the draft modified permit and other information are available for public inspection, Monday through Friday (excluding holidays) from 7:45 a.m. until 4:15 p.m., at the DOH Clean Water Branch (CWB) office located at the 2827 Waimano Home Road 225, Pearl City, HI 96782. Copies may be bought. The public notice permit and fact sheet are also available on the internet at: http://health.hawaii.gov/cwb/site-map/home/public-notices-and-updates. For more information or if you have special needs due to disability that will aid you in inspecting and/or commenting on the public notice permit and related information, please contact Mr. Darryl Lum, Supervisor of the Engineering Section, CWB, at the above address or (808) 586-4309 (Voice) at least seven (7) calendar days before the comment deadline. For those who use a TTY/TDD, please call through Sprint Relay Hawaii, at 1-711 or 1-877-447-5991.
All written comments and requests received on time will be considered. If DOH determines that there is significant public interest, a public hearing may be held after at least 30 calendar days of public notice.
If DOH’s position is substantially unchanged after considering all timely written comments and all oral comments at any public hearing that may be held, then the DOH will issue the NPDES permit and this action will be final.
Please notify anyone you know who would be interested in this matter.
