Definitions. The following words, terms and phrases, when used in this article, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning: Class V injection well means a shallow well used to place a variety of fluids directly below the land surface, which includes a domestic SSTS serving more than 20 people. The U.S. Environmental Protection Agency and delegated state groundwater programs permit these wells to inject wastes below the ground surface provided they meet certain requirements and do not endanger underground sources of drinking water. Class V motor vehicle waste disposal wells and large -capacity cesspools are specifically prohibited (see 40 CFR parts 144 and 146). Cluster system means an SSTS under some form of common ownership that collects wastewater from two or more dwellings or build- ings and conveys it to a treatment and dispersal system located on an acceptable site near the dwellings or buildings. Design flow means the daily volume of wastewater for which an SSTS is designed to treat and discharge. Failure to protect groundwater means at minimum, an SSTS that does not protect groundwater is considered to be a seepage pit, cesspool, drywell, leaching pit, or other pit; an SSTS with less than the required vertical separa- tion distance, described in Minn. R. 7080.1500, subp. 4(D) and (E); and a system not abandoned in accordance with Minn. R. 7080.2500. The determination of the threat to groundwater for other conditions must be made by a qualified employee or an individual licensed pursuant to section 5.24.260. Health authority means the city and its designated agent who shall be a qualified employee or licensee. Imminent threat to public health and safety means, at a minimum an SSTS with a discharge of sewage or sewage effluent to the ground surface, drainage systems, ditches, or storm water drains or directly to surface water; SSTS that cause a reoccurring sewage backup into a dwell- ing or other establishment; SSTS with electrical hazards; or sewage tanks with unsecured, dam- aged, or weak maintenance access covers. The determination of protectiveness for other condi- tions must be made by a qualified employee or an SSTS inspection business licensed pursuant to section 5.24.260. ISTS means an individual sewage treatment system as defined in Minn. R. 7080.1100, subp. 41. Malfunction means the partial or complete loss of function of an SSTS component, which requires a corrective action to restore its intended function. Management plan means a plan that describes necessary and recommended routine operational and maintenance requirements, periodic examina- tion, adjustment, and testing, and the frequency of each to ensure system performance meets the treatment expectations, including a planned course of action to prevent an illegal discharge. Minor repair means the repair or replacement of an existing damaged or faulty component/part of an SSTS that will return the SSTS to its operable condition. The repair shall not alter the original area, dimensions, design, specifications or concept of the SSTS. MPCA means the Minnesota Pollution Control Agency. MSTS means a midsized subsurface sewage treatment system under single ownership that receives sewage from dwellings or other establish- ments having a design flow of more than 5,000 gallons per day to a maximum of 10,000 gallons per day. Notice of noncompliance means a written docu- ment issued by the city notifying a system owner that the owner's onsite/cluster treatment system has been observed to be noncompliant with the requirements of this article.
