Re: Variance request to Chapter 173-160 Washington Administrative Code (WAC)to allow
construction of a water well at 12704 East Highway 106, Washington in the SE '/a, SW
1/4, Section 20, Township 22 North, Range 2 West, W.M., Mason County, (Tax Parcel
No. 22220-34-90131)
Dear Mr. Krug:
This letter is in response to your request for a variance (dated November 17, 2017)concerning
the construction of a well located at 12704 East Highway 106, in Mason County. You are
requesting a variance to the Minimum Standards for the Construction and Maintenance of Wells,
Chapter 173-160 WAC. Specifically, your request is to construct a water well that is located less
than 100 feet from a proposed drainfield. It was determined during the field visit on January 30,
2018,between Davis Drilling and Ecology that the well site is approximately 75 feet from your
existing drainfield. This variance request is necessary due to the location of drainfields on your
property and roadways, driveways, buildings, and the limited land area available to be
developed.
After an investigation, interview and review of information available,a variance is hereby
granted to Chapter 173-160 WAC. Ecology will allow the well to be constructed as soon as
workers and equipment are available and using the method you have proposed. This variance is
granted under the following conditions:
1. This variance is only valid for a period of 1 year after the date of mailing from Ecology.
2. A notice of intent to construct a water well must be filed and the fee paid in accordance
with Section 173-160-151.
3. All well construction work shall be performed by a licensed driller as set forth by
Chapter 173-162 WAC.
4. Well construction must comply with Mason County rules and regulations.
®
5. Due to the close proximity of the onsite septic drainfield,the surface seal shall extend
continuously from the 30 feet deep to land surface, within a significant confining unit
(greater than six feet in thickness). The seal shall provide casing stability and have a
minimum diameter of four inches larger than the nominal size of the permanent casing.
During the installation of the surface seal the driller must use a temporary casing, at least
4-inches larger in diameter than the permanent well casing diameter. Temporary casing
should extend the entire length of the surface seal prior to installation of any sealing
product. Open-hole drilling in an unconsolidated formation without a temporary surface
casing IS NOT APPROVED.
6. Bentonite for the surface seal must be installed as required in Chapter 173-160-231 (2)
and(3). The recent changes to Section-231 require the following: "The annular space
must be kept at least one-half full of sealing material whenever the production casing is
advanced."
7. Due to the close proximity of your driveway and to protect against vehicular damage to
it,the well must be constructed according to the proposed location in your variance
request (at least 75 feet from the drainfield). The well casing stickup must also be one
feet above ground surface. The well must also be protected with two bollards (two metal
posts), cementing in at least 3-inches in diameter metal posts, in a triangular array
between the well casing and adjacent driveway and at least two feet from the well. Each
post must extend at least three feet above and below the land surface.
8. The driller must submit Water Well Reports describing the construction of the well to
Ecology (Southwest Regional office)within 30 days after completion of the work, one
report per well constructed. Attach a copy of this variance to each well report.
9. With the exception of the provisions set forth(above) in this variance, all federal, state,
and local requirements shall apply.
10. The driller must inform Ecology (John Pearch, 360-407-0297)two business days before
any construction work or surface seal installation begins. The driller must make the site
accessible to Mr. Pearch to inspect any and/or all construction work.
11. The driller must inform Mason County (Cody Lund, 360-427-9670 extension 361)two
business days before any construction work or surface seal installation begins. The driller
must make the site accessible to Mr. Lund to inspect any and/or all construction work.
