Current through Register Vol. 49, No. 13, September 23, 2024
Subpart
1.
Purpose.
In order to ensure safe and healthful conditions, to prevent
pollution and contamination of surface and ground waters, and to guide
development compatible with the natural characteristics of blufflands,
shorelands, and related water resources, Saint Croix Riverway ordinances shall
control individual water supply and waste disposal systems with respect to
location, construction, repair, use, and maintenance; and shall control
commercial, agricultural, industrial and public waste disposal, and solid waste
disposal sites.
Subp. 2.
Water supply.
Any public or private supply of water for domestic purposes
shall conform to Minnesota Department of Health standards for water quality.
Private wells shall be placed in areas not subject to flooding and upslope from
any source of contamination.
Subp.
3.
Sewage and waste disposal.
Any premises used for human occupancy shall be provided with
an adequate method of sewage disposal to be maintained in accordance with
acceptable practices.
A. Public or
municipal collection and treatment facilities shall be used where available or
feasible.
B. All private sewage and
other sanitary waste disposal systems shall conform to applicable standards,
criteria, and rules of the Minnesota Department of Health and the Minnesota
Pollution Control Agency, and any applicable local government regulations in
terms of size, construction, use, and maintenance.
C. Location and installation of a septic tank
and soil absorption system shall be such that, with reasonable maintenance, it
will function in a sanitary manner and will not create a nuisance, endanger the
quality of any domestic water supply, nor pollute or contaminate any waters of
the state. In determining a suitable location for the system, consideration
shall be given to the size and shape of the lot, slope of natural and finished
grade, soil permeability, high groundwater elevation, geology, proximity to
existing or future water supplies, accessibility for maintenance, and possible
expansion of the system.
D. Septic
tank and soil absorption systems shall be set back the following distances:
(1) in rural districts, not less than 200
feet from the ordinary high water mark and not less than 40 feet from a
bluffline; and
(2) in urban
districts, not less than 100 feet from the ordinary high water mark and not
less than 40 feet from a bluffline.
E. Soil absorption systems shall not be
allowed in the following areas for disposal of domestic sewage:
(1) low, swampy areas, areas subject to
recurrent flooding, or natural spring areas;
(2) areas where the highest known groundwater
table, bedrock, or impervious soil conditions are within four feet of the
bottom of the system; and
(3) areas
of ground slope which create a danger of seepage of the effluent onto the
surface of the ground.
F. Saint Croix Riverway ordinances may
require or allow alternative methods of sewage disposal, such as holding tanks,
privies, electric or gas incinerators, biological and/or tertiary waste
treatment plants, or land disposal systems, provided such facilities meet the
standards, criteria, and rules of the Minnesota Department of Health and the
Minnesota Pollution Control Agency.
G. Public sewage disposal and commercial,
agricultural, and solid waste disposal shall be subject to the standards,
criteria, and rules of the Minnesota Pollution Control Agency.
