Action Information

Action Date Action Description DEC Staff
9/19/2001 Site Added to Database Petroleum contamination. Bruce Wanstall
9/19/2001 Site Ranked Using the AHRM Preliminary ranking. Bruce Wanstall
1/6/2004 Update or Other Action Request for NFRAP submitted on 11/20/03 by Williams. Shannon & Wilson had installed three soil borings and temporary wells in 2000 for a limited Phase II Assessment. The assessment was completed due to possible transfer of the property to Usibelli Coal. The only contaminant to exceed cleanup levels was DRO in MW-1 at 7.28 mg/L. This well appeared to be placed outside the footprint of the former tank farm. On 11/24/03, Usibelli submitted corrections to the 2000 report. Usibelli noted that the corrections did not change the conclusions of the report. Janice Wiegers
1/6/2004 Update or Other Action Reviewed site information to see if this was the same site as "Williams Healy Tank Farm" File #150.38.023. The Williams Healy Tank Farm is located directly off the Parks HIghway, while this site is located near Sutrana. Janice Wiegers
1/21/2004 Update or Other Action DEC responded to the request for closure and requested delineation of the extent and concentration of soil and groundwater contamination; monitoring to determine groundwater flow direction; and information about possible exposure pathways, including potential for migration to Healy Creek. Janice Wiegers
5/9/2008 Exposure Tracking Model Ranking Initial ranking with ETM completed. Neal Everson
6/15/2009 Update or Other Action Initial ranking corrected due to ETM error in surface water pathway. Mitzi Read

3/23/2018 Update or Other Action Co-ordinated with DEC Division of Water, Usibelli, and Williams regarding application for Rosalie Coal Mine Project. Project would include a haul road running along the south site of this side in the railroad right-of-way. Road construction not likely to happen for about 7 years. Janice Wiegers
7/16/2018 Update or Other Action Site characterization report submitted by Shannon & Wilson. Seven soil boring and co-located temporary well points were installed around the former tank farm. Groundwater flow direction was south-southwest with a gradient of 0.014 to 0.019 foot/foot. Petroleum compounds were present in soil (DRO, naphthalene, ethylbenzene, 1,2,4-trimethylbenzene, and 1,3,6-trimethylbenzene) and groundwater (naphthalene and 1,2,4-trimethylbenzene) above DEC cleanup levels. PAHs were tested in SB17-03 and 1-methylnaphthalene and 2-methylnaphthalene were present above soil cleanup levels. The most contaminated soil sampling location appeared to be SB17-03, which is located approximately 100 feet south of the former tank farm and near the southern property boundary. Some groundwater contamination was found south and southwest of the former tank farm but at low levels. During well development and sampling, temporary wells did not recharge well. One well remained dry and was not sampled. Janice Wiegers
10/29/2018 Update or Other Action Letter sent to responsible party requesting additional site characterization to delineate extent of impacts. Janice Wiegers
