What is the Purpose of this Permit?

What Activities Require this Permit?
The permit is required if clearing, grading or excavating activities disturb an area of 1 acre or more and will discharge stormwater to surface waters of the state or a conveyance system that drains to surface waters of the state. The permit is also required if clearing, grading or excavating activities disturb an area smaller than 1 acre if it is part of a "larger common plan of development or sale" that will disturb 1 acre or more and discharge stormwater to surface waters of the state or a conveyance system that drains to surface waters of the state.
How Much Will this Permit Cost?
Permit fees for Fiscal Year 2013 (July 1, 2012 - June 30, 2013) range from $519 to $1,935 depending on the number of disturbed acres.
Where Can I Get the Application for this Permit?

Do I Need to Include Anything with my Application?

Is the Decision on my Permit Dependent on Anything Besides the Information in my Application?
The applicant must submit the application for coverage on or before the first newspaper publication date of the public notice. Information provided in the public notice must coincide with the application. The State Environmental Policy Act review must be completed before your permit coverage will be issued. As a result of the public notice, Ecology may receive public comment(s) that must be addressed before permit coverage can be issued.
How Long Will it Take to Review my Application?WAC 173-226-200 and RCW 90.48.170: Application for permits shall be made at least 60 days prior to commencement of any proposed discharge or permit expiration date, whichever is applicable.

How Long is my Permit Valid?
The statewide general permit expires every five years, with the current permit set to expire on December 31, 2015. Coverage under the permit is valid until your site's permit coverage is revoked or terminated. If permit coverage is required past the general permit expiration date (December 31, 2015), because construction isn't complete or eligible for termination, the permittee must submit a renewal application to Ecology at least 180 days prior to the expiration date in order to continue permit coverage under the re-issued general permit.
What is the Appeal Process for the Permit?
The permittee and/or a third party may appeal Ecology's decision to cover a site under the Construction Stormwater General Permit within 30 days of issuance. The appeal must be filed in accordance with RCW 43.21B.310.
Notes / Comments:You are encouraged to use the electronic application (eNOI) and submit it to Ecology over the internet, but paper applications are also available in PDF or MS Word formats.
