Site Closure Approved |
Staff reviewed a site assessment conducted at UST 123. The samples collected were well below level "C" criteria.
Based on the data presented in the document, it appears that the site does not exceed the most stringent matrix level "A" criteria. DEC will grant a site closure approved designation for this site. If in the future, additional contamination is discovered at this site, further investigation and/or remedial actions may be requested of the Army by DEC. DEC reserves its rights, under 18 AAC 75, 18 AAC 78 and AS 46.03 to require the Army to conduct additional assessment and/or corrective actions in the future if information indicates the site conditions pose a risk to public health or the environment.
The following policy applies for soil regulated under 18 AAC 75 and 18 AAC 78 that is proposed for disposal off site from where it was generated. If the following criteria is met, ADEC approval and/or an institutional control(s) are not required:
1. The soil meets the most stringent Method Two, Migration to Groundwater, Table B2 cleanup level, and the most stringent standards for those chemicals under Table B1;
2. The soil may only be disposed of at any non-environmentally sensitive location in the Under 40" or Over 40" annual precipitation zone;
3. The soil is not placed within 100 feet of water wells, surface waters, and drainage ditches; and
4.The written approval from the landowner of the off-site location is required.
The off site disposal of all other soil subject to the site cleanup rules that does not meet the criteria above shall be reviewed by the ADEC project manager in order to determine if the off-site disposal action poses a current or future risk to human health or the environment. The final approval to dispose of soil off site that does not meet the criteria shall be made by the ADEC Section Manager.
Terms used in this document have the meaning given in 18 AAC 75.990 including: “environmentally sensitive area” means a geographic area that, in the department's determination, is especially sensitive to change or alteration, including:
(A) an area of unique, scarce, fragile, or vulnerable natural habitat;
(B) an area of high natural productivity or essential habitat for living organisms;
(C) an area of unique geologic or topographic significance that is susceptible to a discharge;
(D) an area needed to protect, maintain, or replenish land or resources, including floodplains, aquifer recharge areas, beaches, and offshore sand deposits;
(E) a state or federal critical habitat, refuge, park, wilderness area, or other designated park, refuge, or preserve; and
(F) an area that merits special attention as defined at 6 AAC 80.170 (Repealed see AS 46.40.210(1))
“area which merits special attention” means a delineated geographic area within the coastal area which is sensitive to change or alteration and which, because of plans or commitments or because a claim on the resources within the area delineated would preclude subsequent use of the resources to a conflicting or incompatible use, warrants special management attention, or which, because of its value to the general public, should be identified for current or future planning, protection, or acquisition; these areas, subject to council definition of criteria for their identification, include:
(A) areas of unique, scarce, fragile or vulnerable natural habitat, cultural value, historical significance, or scenic importance;
(B) areas of high natural productivity or essential habitat for living resources;
(C) areas of substantial recreational value or opportunity;
(D) areas where development of facilities is dependent upon the utilization of, or access to, coastal water;
(E) areas of unique geologic or topographic significance which are susceptible to industrial or commercial development;
(F) areas of significant hazard due to storms, slides, floods, erosion, or settlement; and
(G) areas needed to protect, maintain, or replenish coastal land or resources, including coastal flood plains, aquifer recharge areas, beaches, and offshore sand deposits. |
