General Permit Authorization Number: AKR10H031

This email/letter acknowledges that you have submitted a Notice of Intent (NOI) form to be covered under the APDES General Permit for Stormwater Discharges for Construction General Permit Activity (Construction General Permit) and is assigned the permit authorization number: AKR10H031. Please reference your permit authorization number in all future correspondence. The permittee is authorized to discharge storm water under the terms and conditions of this permit upon the issuance date of this letter and expires January 31, 2026 or as per Permit Part 2.6. Permit documents will be posted to the Alaska DEC EDMS Map Explorer at https://dec.alaska.gov/Applications/Water/EDMS/nsite.

According to the NOI information provided (ref: HPK-P99V-JBYD3, recd: 08/15/2022), the location of the SWPPP or the name and telephone number of the contact person for scheduling SWPPP viewing times is as follows:

• SWPPP Location: 2901 E. Bogard Road, Suite 103, Wasilla, 99654

• SWPPP Contact: Stephen Morrow, FHWA Western Federal Lands Highway Division, Environmental Protection Specialist, (360) 619-7700, stephen.morrow@dot.gov, 610 E 5TH ST, Vancouver, WA 98661

Note, as per Permit Part 2.7 the permittee is required to submit a modification NOI within 30 calendar days if any of the following change: Owner/Operator address and contact information, site information, estimated start or end dates, acres disturbed, or SWPPP location and contact information.

Coverage is not transferable. The permittee must submit a Notice of Termination (NOT) instead of an NOI modification to DEC within 30 calendar days when the operator has changed. A change of operator in this case means when an organization changes control of the project. It does not mean when a corporate officer of the organization changes while the organization continues with the project. The new owner/operator must file a new NOI to obtain coverage under the CGP.

A permittee must submit an NOT within 30 calendar days when final stabilization has been achieved on all portions of the site, in accordance with Permit Part 4.5.2 for which the permittee is responsible, all ground disturbing construction activity or use of support activities has been completed, and all temporary Best Management Practices (BMP’s) have been removed; or a new permittee has assumed control over all areas of the site that have not been finally stabilized.

1.0 COVERAGE UNDER THIS PERMIT

1.1 Introduction

The Alaska Construction General Permit (CGP) authorizes storm water discharges from large and small construction-related activities that result in a total land disturbance of equal to or greater than one acre and where those discharges enter waters of the U.S. (directly or through a storm water conveyance system) or a municipal separate storm sewer system (MS4) leading to waters of the U.S. subject to the conditions set forth in this permit. This permit also authorizes storm water discharges from certain construction support activities and some non-storm water discharges commonly associated with construction sites.

The goal of this permit is to minimize erosion and reduce or eliminate the discharge of pollutants, such as sediment carried in storm water runoff from construction sites through implementation of appropriate control measures. Polluted storm water runoff can adversely affect fish, animals, plants, and humans. In order to ensure protection of water quality and human health, this permit describes control measures that must be used to manage storm water runoff during construction activities. This permit replaces the CGP that became effective February 1, 2016 and expired on January 31, 2021.

1.2 Person(s) Responsible for Obtaining Authorization under this Permit

1.2.1 All operators of large or small construction activities that meet the conditions in Part 1.4 must obtain authorization under this permit. For the purposes of this permit, an “operator” is any party associated with a construction project that meets either of the following two criteria:

1.2.1.1 The party has operational control over construction plans and specifications, including the ability to make modifications to those plans and specifications, or

1.2.1.2 The party has day-to-day operational control of those activities at a project that are necessary to ensure compliance with the permit conditions (e.g., they are authorized to direct workers at a site to carry out activities required by the permit)

Note: Subcontractors generally are not considered operators for the purposes of this permit.

Note: Where there are multiple operators associated with the same project, all operators are required to obtain permit authorization. The following applies in these situations:

• If one operator has control over plans and specifications and a different operator has control over activities at the project site, they may divide responsibility for compliance with the terms of this permit as long as they develop a group storm water pollution prevention plan

(SWPPP) (see Part 5.1), which documents which operator has responsibility for each requirement of the permit.

• If an operator only has operational control over a portion of a larger project (e.g., one of four homebuilders in a subdivision), the operator is responsible for compliance with all applicable effluent limits, terms, and conditions of this permit as it relates to the activities on their portion of the construction site, including protection of endangered species, critical habitat, and historic properties, and implementation of control measures described in the

SWPPP in the areas under their control.

• An operator must ensure either directly or through coordination with other permittees, that their activities do not render another permittee’s pollutant discharge controls ineffective.

1.3 Permit Area

This general permit covers the State of Alaska, except lands within the Metlakatla Indian

Reservation and the Denali National Park and Preserve.

1.4 Eligibility

1.4.1 Eligibility Requirements. To be authorized under this permit, the project must meet the following conditions or be notified by DEC that the site is eligible for permit coverage.

1.4.1.1 The project will disturb one or more acres of land, or will disturb less than one acre of land but is part of a common plan of development or sale that will ultimately disturb one or more acres of land;

1.4.1.2 The site will discharge storm water to waters of the U.S. (directly or through a storm water conveyance system) or a MS4 leading to a waters of the U.S.;

1.4.1.3 The project area is located in an area where DEC is the permitting authority;

1.4.1.4 The project is not already covered under a different APDES permit;

1.4.1.5 The project does not discharge to an impaired waterway with an EPA-approved or established Total Maximum Daily Load (TMDL) that specifically precludes such discharges; and

1.4.1.6 The project is not likely to jeopardize the continued existence or cause a take of any threatened or endangered species protected under the Endangered Species Act (ESA) or their designated critical habitat.

1.4.2 Authorized Storm Water Discharges. Subject to compliance with the terms and conditions of this permit, the following discharges are authorized under this permit:

1.4.2.1 Storm water discharges associated with large and small construction activities, including those that are part of a common plan of development or sale that will ultimately disturb one or more acres of land.

1.4.2.2 Storm water discharges designated by DEC as needing a storm water permit under

40 CFR §122.26(a)(1)(v) or §122.26(b)(15)(ii).

1.4.2.3 Storm water discharges from support activities (such as concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas) (as defined in Appendix C), whether on-site, adjacent to, or off-site, provided:

1.4.2.3.1 The support activity is directly related to the construction site required to have permit authorization for discharges of storm water associated with construction activity under this permit:

1.4.2.3.2 The support activity is not a commercial operation serving multiple unrelated construction projects by different permittees;

1.4.2.3.3 The support activity does not operate beyond the completion of the construction activity at the project it supports; and

1.4.2.3.4 Appropriate control measures are identified in the Storm Water Pollution

Prevention Plan (SWPPP) and pollutant discharges are minimized in compliance with Parts 3.0 and 4.0 of the permit.

1.4.2.4 Discharges composed of allowable discharges listed in Parts 1.4.2 and 1.4.3 commingled with a discharge authorized by a different APDES permit and/or a discharge that does not require APDES permit authorization.

http://www.ecfr.gov/cgi-bin/text-idx?SID=cd32add828dfbfd32ccadd72afd59a58&mc=true&node=se40.22.122_126&rgn=div8 http://www.ecfr.gov/cgi-bin/text-idx?SID=cd32add828dfbfd32ccadd72afd59a58&mc=true&node=se40.22.122_126&rgn=div8

1.4.3 Authorized Non-Storm Water Discharges. Subject to compliance with the terms and conditions of this permit, the following non-storm water discharges are authorized under this general permit, provided the non-storm water component of that the discharge is in compliance with the SWPPP requirements in Part 5.3.9:

1.4.3.1 Discharges from fire-fighting activities;

1.4.3.2 Fire hydrant flushings;

1.4.3.3 Waters used to wash vehicles where detergents are not used;

1.4.3.4 Water used to control dust;

1.4.3.5 Potable water including uncontaminated water line flushings;

1.4.3.12 Landscape irrigation.

1.4.4 Limitations on Coverage. The following discharges are not authorized under this permit:

1.4.4.1 Post-Construction Discharges. Discharges that originate from the project after construction activities have ceased and a Notice of Termination (NOT) has been submitted in accordance to Part 10.0, including any temporary support activity.

1.4.4.2 Discharges that May Exceed Water Quality Standards. Discharges that DEC, prior to authorization under this permit, determines will cause, have the reasonable potential to cause, or contribute to an excursion above any applicable water quality standard

(WQS). Where such a determination is made prior to authorization, DEC may notify the applicant that an individual permit application is necessary in accordance with Part

2.8. However, DEC may provide permit authorization after the applicant has included appropriate controls and implementation procedures designed to bring the discharge into compliance with WQS’s in accordance with Part 3.1.

1.4.4.3 Discharges to Water Quality Impaired Waters. Discharges into receiving waters that are listed as impaired waters in the report Alaska’s Final 2018 Integrated Water

Quality Monitoring and Assessment Report, dated March 26, 2020 (or the most current

EPA-approved version), or with an approved or established TMDL analysis, unless the discharges are in accordance with Part 3.2.

1.4.4.4 Comingled Discharges. Discharges that are mixed with non-storm water, unless they are listed as allowable non-storm water discharges in Part 1.4.3.

2.3 How to Submit an Notice of Intent (NOI)

2.3.1 Submittal Options. Each operator must submit an NOI to be authorized to discharge under this permit at least five business days prior to commencement of construction activities. DEC may need additional time for manual processing of NOIs. The complete and accurate NOI can be submitted either:

2.3.1.1 Electronically (strongly encouraged): Go to DEC’s Water Online Application System

(OPA) web page at http://dec.alaska.gov/water/oasys/index.html to prepare and submit electronic NOI (eNOI). Note the eNOI will likely be processed more quickly and result in faster receipt of an authorization to discharge.

2.3.1.2 Paper NOI Form: Complete the CGP NOI form on DEC’s APDES Storm Water

Forms web page at http://dec.alaska.gov/water/wnpspc/stormwater/2016CGPForms.htm. Once the form is complete, scan and email the entire form (5 pages) to the permitting email address in

Appendix A, Section 1.1.1 or submit a paper copy to DEC at the address listed in

Appendix A, Section 1.1.1.

2.3.1.3 Applicants must pay the general permit authorization fee (in accordance with 18 AAC

72.956) before their NOI is considered complete.

2.4 Submission Deadlines

2.4.1 New Projects. The operator must submit a complete and accurate NOI and SWPPP (if project disturbs five or more acres in accordance with Part 2.1) prior to commencement of construction activities consistent with Parts 2.2.1 and 2.3 to obtain authorization under this permit.

2.4.2 Permitted Ongoing Projects.

2.4.2.1 An ongoing permitted project is one that commenced construction activities prior to the effective date of this permit and where the discharges from that project were authorized under the 2016 CGP (AKR100000). To continue coverage, a permittee must:

2.4.2.1.1 Continue to comply with the terms and conditions of the 2016 CGP until the permittee has been granted authorization under this permit or an alternative

APDES permit, or submits a NOT;

2.4.2.1.2 Update the existing SWPPP as necessary to comply with the requirements of Part

3.0, Part 4.0 and Part 5.0 before submitting a new NOI, as described in Part

2.4.2.1.3; and

2.4.2.1.3 Submit a complete and accurate new NOI within 90 calendar days of the effective date of this permit according to Part 2.3. A copy of the updated SWPPP and permit fee is not required to be submitted with the NOI to DEC for permitted ongoing projects.

2.4.2.2 If the permittee is eligible to submit a NOT (e.g., construction is finished and final stabilization has been achieved) before the 90th day, a new NOI is not required to be submitted provided a NOT is submitted within 90 calendar days after the effective date of this permit.
