WAC 173-175-010 Purpose and authority. These regulations provide for the comprehensive regulation and supervision of dams in order to reasonably secure safety to life and property pursuant to chapters 43.21A, 43.27A, 86.16, 90.03, 90.28, and 90.54 RCW. The purposes of these regulations are to:
(1) Designate the types of dams to which these regulations are applicable;
(2) Provide for the design, construction, operation, maintenance, and supervision of dams in a manner consistent with accepted engineering practice;
(3) Establish and administer a program for permitting of construction work for new dams and for modifications of existing dams;
(4) Establish a fee schedule based on dam size that will reflect the actual cost to the department of engineering review of plans and specifications and for construction inspections;
(5) Establish the requirements and owner responsibilities for developing and executing plans for operation and maintenance, owner inspection and emergency actions; and
Encourage owners to establish a program for the
periodic inspection of their projects.)) Establish a program
for the periodic inspection by the department of existing
dams, and a fee schedule for these inspections based on
downstream hazard classification and frequency of inspections.
This fee schedule will reflect the actual cost to the

The ten acre-feet threshold applies to any dam which can impound water of any quality, or which contains any substance in combination with sufficient water to exist in a liquid or slurry state at the time of initial containment.
(2) For a dam whose dam height is six feet or less and which meets the conditions of subsection (1) of this section, the department may elect to exempt the dam from these regulations.
The decision by the department to exempt a dam will be made on a case-by-case basis for those dams whose failure is not judged to pose a risk to life and minimal property damage would be expected (downstream hazard class 3).
(3) These regulations do not apply to dams that are, or will be, owned, by an agency of the federal government which has oversight on operation and maintenance and has its own dam safety program for periodic inspection and repair of safety deficiencies of completed projects. The department will continue to be the state repository for pertinent plans, reports, and other documents related to the safety of federally owned dams.
(4) These regulations do not apply to transportation facilities such as roads, highways, or rail lines which cross watercourses and exist solely for transportation purposes and which are regulated by other governmental agencies.
Those transportation facilities which cross watercourses and which have been, or will be, modified with the intention of impounding water on an intermittent or permanent basis and which meet the conditions of subsection (1) of this section shall be subject to these regulations.
(5) These regulations do not apply to dikes or levees constructed adjacent to or along a watercourse for protection from natural flooding or for purposes of floodplain management.
(6) These regulations do not apply to concrete or steel water storage tanks.
(7) These regulations do not apply to FERC licensed projects and to FERC exempted projects. The department will continue to maintain a repository for pertinent plans, reports, and other documents related to the safety of FERC licensed and FERC exempted projects.

(e) Surficial inspections of low hazard dams.
(2) No fees shall be charged to the dam owner for nonroutine inspections.
(a) Impounds ten or more acre-feet of water at the dam crest level; and
(b) Is endangering public safety or property, or has been constructed without prior department approval.
(2) The department shall provide a copy of the written report of findings to the complainant and dam owner.
(3) The dam owner shall be required to correct any identified safety deficiencies or exigency conditions in a timely manner.
(4) Dams found to be under construction or recently built without prior approval of the plans and specifications will be subject to enforcement actions as described under WAC 173-175-620(2).
(5) No fees shall be charged to the dam owner for inspections at public request.
PERIODIC INSPECTION FEES
WAC 173-175-755 Periodic inspection fees. The department is required by RCW 90.03.470(8) to collect in advance the actual cost, including the expense incident thereto, of the inspection of any dam to insure safety to life and property. Fee amounts contained in this section represent the department's true estimate of the cost of performing periodic dam safety inspections as described in WAC 173-175-705, and reflect the department's commitment to fully recover all eligible expenses.
(a) Equation 1 below is used to calculate the annual inspection fees.
|Annual Inspection Fee||=||(COSTFGF)||÷||(Cycle)||Equation 1|
(i) Cycle = number of years between inspections, with five years being the minimum.
(ii) FGF = an annual fiscal growth factor expressed as a percentage, as determined under chapter 43.135 RCW.
(iii) COSTFGF = cost of inspection in dollars including a fiscal growth factor. The cost is obtained by multiplying the inspection cost in the preceding year by the current year's fiscal growth factor as follows:
|COSTFGF||=||Previous year's cost x [1 + (FGF)] Equation 2|
(c) The cost for an inspection by the department in the base year will be as follows:
(i) $3440.00 for dams with high downstream hazard classifications, with a prorated annual fee of $688.00 for a five-year inspection cycle.
(ii) $2500.00 for dams with significant downstream hazard classifications, with a prorated annual fee of $500.00 if a five-year inspection cycle is implemented, or $250.00 if a ten-year inspection cycle is implemented.
(2) Inspection fee for impoundments with multiple dams. For reservoirs or impoundments with a main dam and one or more saddle dams, a single annual inspection fee will be charged for the facility. The dam with the highest downstream hazard rating will be used for fee computation.
(3) Inspection fee for multicell impoundments. For multicell impoundments, such as wastewater lagoons, where two or more cells are located side-by-side or share a common embankment, a single annual inspection fee will be charged for the facility. The cell with the highest downstream hazard classification will be used for fee computation.
(4) Inspection fee for nonroutine inspections. For nonroutine inspections as described in WAC 173-175-725, no fees will be charged to the dam owner.
(5) Inspection fee for inspections at public request. For inspections done at public request, as described in WAC 173-175-735, no fees will be charged to the dam owner.

WAC 173-175-775 Periodic inspection fee computation. (1) The department shall charge inspection fees based on the fee schedule contained in WAC 173-175-765. After July 1st of each year, the department shall publish the adjusted fees by providing notice on its internet site, and by providing written notification by mail or electronic mail to owners of high and significant hazard dams. The inspection fees must be received by the department within forty-five days after the department mails a billing statement.
(2) Inspection fee computation. Computation of fees shall begin on the first day of each fiscal year. In the case of new dams not previously covered by the inspection program, fee computation begins on the first day of each fiscal year following completion of construction.

(2) In the event a check is returned due to insufficient funds, the department shall consider the inspection fee to be unpaid.
(3) Delinquent accounts. Dam owners are considered delinquent in the payment of fees if the fees are not received by the first invoice billing due date. Delinquent accounts will be processed in the following manner:
(a) Municipal and government entities shall be notified by certified mail that they have one hundred eighty days to bring the delinquent account up-to-date. Regulatory orders may be issued to enforce a restriction of reservoir filling until all delinquent fees are paid on accounts that remain delinquent after ninety days.
(b) Nonmunicipal or nongovernment dam owners shall be notified by the department by certified mail that they have one hundred eighty days to bring the delinquent account up-to-date. Accounts that remain delinquent after one hundred eighty days may be turned over for collection. In addition, a surcharge totaling twenty percent of the delinquent amount owed will also be added. The surcharge is to recover the costs for collection. If the collection agency fails to recover the delinquent fees after twelve months, the department may issue regulatory orders to enforce restriction of reservoir filling until all delinquent fees are paid.
