RE: T12N R3W SEC13 Lot 8 S2
1000-gallon concrete septic tank, 150 sf shallow trench drain field
Maximum Daily Flow: 150 GPD
Conditional Construction Approval
Steve Pannone:
On 1/15/2025, the Alaska Department of Environmental Conservation (ADEC or Department) received a
submittal requesting construction approval for T12N R3W SEC13 Lot 8 S2 located in Anchorage. The
information was reviewed in accordance with Wastewater Disposal Regulations 18 AAC 72 and conditional
construction approval is granted.
Project Description
The system is designed to serve commercial facilities with a flow rate of 150 GPD. The approved wastewater
treatment and disposal system will include a 1,000-gallon D&S concrete septic tank and a soil absorption system
with an area of 150 SF.
The absorption system will measure 5 feet in width and 30 feet in length, along with the necessary piping and
wiring. The drainage bed will consist of 12 inches of drain rock placed over a 2-feet layer of sand. Effluent from
the septic tank will be distributed through a perforated 4-inch diameter SDR 35 PVC pipe.
To prevent the mound from freezing, there will be a minimum of 4 inches of rigid foam insulation along with 2
feet of soil cover.
Fresh water will be supplied to the facilities by an onsite private well.
Construction Approval Conditions
1. The groundwater level may change over time due to seasonal variations. It is necessary to confirm the
groundwater levels again during the construction phase to ensure that a minimum separation distance
from the drain rock is maintained.
Approval to Operate Requirements
This construction approval includes a 90 day interim approval to operate provided that construction substantially
complied with the approved design drawings. In order to receive final operational approval, please submit the
following information within 60 days of the completion of this project:
Steve Pannone 2
T12N R3W SEC13 Lot 8 S2 1/24/2025
1. Written request for operational approval that includes a statement regarding any changes made during
construction
2. Record drawings prepared (signed and dated) by the engineer responsible for observing the construction
of this project (The Department prefers drawings that are no larger than 11 x 17.)
3. Certification of Construction form complete with signatures from the Owner, Construction Contractor,
and Engineer (A copy of this form may be downloaded and printed from the Department of
Environmental Conservation website or a copy will be provided upon request.
dec.alaska.gov/water/wastewater/engineering/engineered-systems)
If the approval to operate requirements cannot be met within 90 days of construction completion, an extension of
the interim approval to operate must be requested at least 30 days in advance by addressing item 3 above.
Disclaimers
Approval of submitted plans is not approval of omissions or oversights by this office or noncompliance with any
applicable regulation. The Department's construction approval does not guarantee correctness or the functionality
of the design, or waive the owner's responsibility for continued compliance with state regulations. Deviations from
approved plans which affect capacity, flow, pressure, operation, compliance, or materials of major system
components must be approved by this Department prior to their construction or implementation.
This approval is valid for two years from the date of this letter. If the applicant fails to construct, alter, install,
or modify the system, the approval is void and plans must be resubmitted for department review and approval
according to 18 AAC 72.200.
This approval is contingent upon your receipt of any other state, federal, or local authorizations which are
required for your project. You are required to obtain all other necessary authorizations before proceeding with
your project. This approval does not imply the granting of additional authorizations nor obligate any state, federal,
or local regulatory body to grant required authorizations.
Informal Reviews and Adjudicatory Hearings
A person authorized under a provision of 18 AAC 15 may request an informal review of a contested decision by
the Division Director in accordance with 18 AAC 15.185 and/or an adjudicatory hearing in accordance with 18
AAC 15.195 18 AAC 15.340. See DECs Appeal a DEC Decision web page
https://dec.alaska.gov/commish/review-guidance/ for access to the required forms and guidance on the appeal
process. Please provide a courtesy copy of the adjudicatory hearing request in an electronic format to the parties
required to be served under 18 AAC 15.200. Requests must be submitted no later than the deadline specified in 18
AAC 15.
