State of Wyoming Public Notice

WYR320000 – Renewal of the Mineral Mining General Permit for Storm Water Discharges

 

The purpose of this notice is to invite your comments on the proposed permit before it is issued.  Copies of the proposed permit are available on our website at http://deq.wyoming.gov/wqd/public-notices/water-wypdes/.  Additionally, upon request, a copy of the draft permit and other pertinent documents are available at the address listed below.  Copies may also be requested by calling 307-777-7781.  A complete copy of the permit file will be retained at the DEQ/WQD Cheyenne office.  The permit file contains the proposed permit, fact sheet and other pertinent information.

Comments on the proposed permit must be submitted in writing to John Gorman; DEQ/WQD; 200 West 17th Street; Cheyenne, WY  82002 by 5:00 pm, April 28, 2017.  Questions regarding the proposed permit may be directed to John Gorman (307-777-5622).  All comments must be received in writing or as fax copies of written comments.  Comments received by e-mail will not be accepted.

Any interested person may submit written comments on a proposed permit and may request a public meeting.  A request for a public meeting shall be in writing and shall indicate the interest of the party and the reasons why a meeting is warranted.  If the administrator finds that there is a significant degree of public interest he may facilitate such a public meeting.  The DEQ/WQD will consider all comments when making the final decision of issuance or denial of the permit and the decision may be appealed to the Wyoming Environmental Quality Council (EQC).

The current mineral mining general permit (MMGP) expires March 31, 2017.  A draft permit has been prepared to replace the current permit.  Please note that the current permit will be administratively continued until a new permit is issued.  There will be no lapse in coverage. 

This permit covers storm water discharges from all mineral mining activities (except fuels).  The permit requires mineral mining facility operators to develop and implement a plan to ensure that storm water discharged from their project does not cause or contribute to a violation of water quality standards in surface waters receiving that discharge.  The permit covers all areas of Wyoming except certain areas within the Wind River Indian Reservation where the state does not have jurisdiction.
