BEFORE THE DEPARTMENT OF ENVIRONMENTAL QUALITY
OF THE STATE OF MONTANA
In the matter of the amendment of ARM 17.56.607 pertaining to release categorization
AMENDED NOTICE OF PUBLIC HEARING ON PROPOSED AMENDMENT
(UNDERGROUND STORAGE TANKS)
TO: All Concerned Persons
1. On August 7, 2014, the Department of Environmental Quality published MAR Notice No. 17-364 regarding a notice of public hearing on the proposed amendment of the above-stated rule at page 1663, 2014 Montana Administrative Register, Issue Number 15. The department is publishing this amended notice to correct an error in the original notice. On September 24, 2014, at 1:30 p.m., the Board of Environmental Review will hold a public hearing in Room 111, Metcalf Building, 1520 East Sixth Avenue, Helena, Montana, to consider the proposed amendment of the above-stated rule in the manner shown below. The rule should have been and is now proposed as follows, stricken matter interlined, new matter underlined:
17.56.607 RELEASE CATEGORIZATION (1) through (9)(g) remain the same.
(10) The department may categorize a release as resolved with a petroleum mixing zone and send a letter to the owner or operator in accordance with (11), if the department has determined that conditions at the site ensure present and long-term protection of human health, safety, and the environment and that residual petroleum in soil and ground water will continue to be remediated through natural attenuation processes without additional intervention, active cleanup, or monitoring. The following requirements must also be met before a release may be categorized as resolved with a petroleum mixing zone:
(a) through (h) remain the same.
(i) at the downgradient boundary of a petroleum mixing zone, the concentration of any petroleum constituent does not exceed a water quality standard adopted by the Board of Environmental Review pursuant to 75-5-301, MCA. The downgradient boundary of a petroleum mixing zone must be determined by documented investigations conducted in accordance with ARM 17.56.604.
A a petroleum mixing zone must remain within the facility property boundary unless a recorded easement approved by the department allows the mixing zone to extend off the facility property. A petroleum mixing zone may extend no further than 500 feet from the origin of the release. For purposes of this rule, the term "facility property" means a single parcel or contiguous parcels on which one or more petroleum storage tanks are or were located, provided that contiguous parcels must be under single ownership at the time the petroleum mixing zone is established;
(j) a petroleum mixing zone may not extend to within 500 feet of an existing drinking water well or surface water;
(k) a petroleum mixing zone may not extend either beyond 500 feet from the origin of the release or within 500 feet of an existing drinking water well or surface water unless the department determines, in writing and based on site-specific circumstances, that distances not meeting the 500-foot criteria, as specified in the determination, will ensure present and long-term protection of human health and safety and of the environment in the specific circumstances. In making this determination, the department shall consider the following factors:
(i) the specific contaminants and concentrations involved;
(ii) the nature, hydrogeologic characteristics, and quality of the aquifer(s) involved;
(iii) the nature and quality of any well or surface water potentially affected;
(iv) the degree of certainty that site-specific scientific data supports the determinations made pursuant to (c), (d), (g), and (h); and
(v) any other consideration determined by the department to be relevant in the particular circumstances.
(k) through (k)(iv) remain the same, but are renumbered (l) through (l)(iv).
(l) (m) a notice is placed on the deed of all parcels of real property on which the facility is located that is the source of the release is resolved with a petroleum mixing zone release is located. This deed notice must describe the nature and location of the residual contamination remaining in the soil and ground water at the facility and must describe all institutional controls, engineering controls, physical conditions, or other controls or conditions required to maintain the petroleum mixing zone.
(11) and (12) remain the same.
AUTH: 75-11-319, 75-11-505, MCA
IMP: 75-11-309, 75-11-505, MCA
3. This change is being made because, as indicated in the statement of reasonable necessity, the purpose of the rulemaking is to allow mixing zones in certain instances to (a) come closer than 500 feet to an existing drinking water well or surface water or (b) extend more than 500 feet from the source of the contamination. Use of the term "a shorter distance" in proposed ARM 17.56.607(10)(k) was not consistent with the second purpose.
