| 2522813 | Primary Facility | 2016-07-14 | Complaint Inspection | Violation(s) Noted | On 7/14/16, I performed a complaint inspection for the following sites in response to complaint number 320942 and made the following observations:
•Eakin 1: A moderate erosion channel was observed running along the site access road. Black staining was noted around well head/equipment indicating a spill of petroleum product. This constitutes a violation of 25 Pa. Code § 78.54 for failing to control or dispose of oil in a manner that prevents pollution to the Waters of the Commonwealth. •Eakin 2: There appears to be an area of wetlands as evidenced by the presence of wetland vegetation is noted to be in close proximity to this well. Special caution is advised to prevent contamination of Waters of the Commonwealth. •Eakin 3: Due to heavy vegetation including poison ivy and other noxious species around well equipment only limited inspection was possible. Continued failure to maintain a site in such a state as to allow for inspection can constitute a violation of the well permit conditions. Remediation a |
