Mont. Admin. r. 17.24.1818 - WATER QUALITY: IMPOUNDMENT
(1) Treatment
facilities in sufficient size and number consisting of but not limited to collection
basins, water retarding structures and siltation dams shall be constructed with
prior approval of the department. All such facilities shall be constructed at or
above the points of discharge into receiving streams for the purpose of treating
acid or toxic water and for the settling of sediment prior to discharge into the
receiving stream. As part of an application for permit, an operator shall submit the
design specifications, drawings, method of operation and control, and quality of
discharge of the treatment facilities. The operator shall indicate on the maps
submitted as part of an application for permit the proposed location of all
treatment facilities. Proposed reclamation of treatment facilities shall be included
in the reclamation plan. Additional treatment facilities may be required by the
department after commencement of the operation if conditions so indicate a
need.
(2) All approved and constructed
treatment facilities shall be maintained in proper working order by the operator and
operated so that they will perform as proposed in the application for permit. All
treatment facilities constructed and approved pursuant to the provisions of this
rule shall be monitored by the operator to assure continuous satisfactory
performance until approved reclamation has been accomplished.
(3) Permanent water impoundments shall not be
allowed unless approved by the department. If the department determines at any time
that the proposed impoundment area will not fill to the expected levels, meet
acceptable water quality standards or any other relevant criteria, the impoundment
area shall be regraded and surface drainage facilitated.
(4) No water quality treatment of approved lakes
or ponds shall be permitted without department approval.
(5) Monthly monitoring reports, where applicable,
shall be submitted to the department including the number of operating days, the
gallons of drainage treated, a log of the tests made in accordance with ARM
17.24.1819, and a description of any
operating problems and the corrective action taken.
