(1) (a) Except for primitive campgrounds, an adequate and safe sewage system must be provided in each campground or trailer court for conveying, treating and disposing of all sewage. In addition, all campground and trailer court operators must take immediate measures to alleviate health and sanitation hazards caused by sewage at the campground or trailer court.

(b) Under this subchapter, a limited services campground may use a sealed vault pit privy or alternative system approved by the department for sewage disposal, provided the system does not place sewage in a location likely to cause pollution of state waters, in violation of Title 75, chapter 5, MCA, or pose potential adverse public health effects. Other regulations, including local ordinances, may preclude use of such systems.

(2) An operator of a public sewage system serving a campground or trailer court must be certified in compliance with Title 37, chapter 42, MCA.

(3) A sewage system has failed and requires replacement or repair if any of the following conditions occur:

(a) The system fails to accept, treat, or dispose of sewage as designed;

(b) Effluent from the sewage system contaminates a potable water supply or state waters; or

(c) The sewage system is subjected to mechanical failure, including electrical outage, or collapse or breakage of a septic tank, lead line, or drainfield line.

(4) Extension, alteration, or replacement of any sewage system must be in accordance with ARM 17.36.301 through 17.36.305 and, if the system is a public sewage system, ARM 17.38.101 and 17.38.105.

(5) Provisions must be made for plugging or capping the sewer riser pipe with a tamper resistant cap when a trailer does not occupy the space. The cap must provide an air tight seal.

(6) Liquid wastes from sinks, showers, toilets, or baths are not allowed to accumulate on the ground surface. Such waste must be discharged into the sewage system serving the trailer court or campground or into an alternate system approved by the department and local health authority.

(7) The department hereby adopts and incorporates by reference the provisions of ARM 17.36.301 through 17.36.305, setting standards for sewage treatment and disposal systems; and 17.38.101 and 17.38.105, setting requirements for public water and sewer plans and cross connections.
