Subject:
Henderson Loop Sanitary Sewer Improvements, Holly Hills Subdivision,
ADEC Project Number 9321-DWW-016 and 9321-WV-013, Review
Dear Mr. Lang:
I have reviewed your October 5, 1992 submittal, the letters of non- objection from owners
of the effected water systems and hydrogeological information that I could find on the
area. Based on this review, I have the following comments.
The information I have been able to uncover on the quality of water being provided from
the two Class C Public Water Systems' effect by the proposed sewer line verifies that
maximum contaminant concentration levels for total coliform bacteria and nitrates (as
nitrogen) found in the State Drinking Water Regulations are currently being met.
However, the waiver requests did not include the information required in either 18 AAC
72.015(b) and 18 AAC 80.030. From my research, it is apparent that site conditions are
such that without special construction specifications/requirements, the waivers, as
requested, could not be granted.
As noted above, the requested waivers are feasible only due to the special construction
specifications that are being proposed. In addition, the sewer line is required to resolve
the problem that has been caused by a failing soil absorption system on Lot 6, Block 1.
Therefore, in accordance with the Provisions of 1'8 AAC 72.015 Wastewater Disposal
Regulations and 18 AAC 80.030 Drinking Water Regulations, the following waivers are
granted:
Lot 6, Block 1
From Class C Public Water System Source Well
-To manhole at Sta. 1 +95.00 from 150 feet to 115 feet
-To manhole at Sta. 3+16.00 from 150 feet to 26 feet
Kenneth G. Lang 2 October 13, 1992
-To private sewer line on lot 6 from 75 feet to 38 feet at the closest point.
-To community sewer line from ! 50 feet to 29 feet at the closest point
Lot 2, Block 2
From the Class C Public Water System Source Well
-To manhole at Sta. 1 + 95.00 from 150 feet to 146 feet
-To manhole at Sta. 3 + 16.00 from 150 feet to 63 feet
-To Community sewer line from 150 feet to 65 feet at the closest point
Lot 3, Block 2
From a private water system source well to the Manhole at Sta. 3+ 16.00 from 100
feet to 94 feet
These
Lot 8, Block 1
From a private water system source well to the manhole at Sta. 3+ 16.00 from 100
feet to 90 feet.
waivers will remain valid, as long as the following requirements are addressed.
1. Restrained joints with heat sink sleeves are used for all joints with the 150
foot protective radii of the Class C Public Water System Source Wells
located on Lot 6, Block 1 and Lot 2, Block 2 of Holly Hills Subdivision.
2. Water tight manholes will be used as noted on the submitted construction
drawings.
3. The eight inch sanitary sewer main and the six sanitary sewer services will
need to be water pressure tested prior to acceptance.
4. The owner of the Class C Public Water Source Well will need to sample the
Well on Lot 6, Block 1 Holly Hills Subdivision once every three months and
Nitrate (as Nitrogen) in February and September each year.
The Public Water System Identification Number (PWSlD #) assigned to the Class C Public
Water System on Lot 6, Block 1, Holly Hills Subdivision is 217893.. This number will need
to be included on all testing results submitted to the Department. This is to ensure that
the results will be recorded to the proper public water system to validate the existing
waivers.
These approvals do not imply the granting of any additional authorizations, nor obligate
any state, federal, or local regulatory body to grant required authorizations.
Kenneth G. Lang
do not hesitate to contact me.
