Pinnacle Engineering was retained to assist with environmental compliance tasks associated with a crude oil rail loading facility in North Dakota. The facility is located on tribal land and is under the regulatory purview of the U.S. Environmental Protection Agency (EPA), the U.S. Army Corps of Engineers (ACOE), and the tribal environmental department. Pinnacle provides a wide range of ongoing environmental compliance services for this facility, including the following:

  • Pinnacle conducts monthly Volatile Organic Compound (VOC) emission calculations in accordance with the facility’s air permit.
  • Pinnacle conducted the initial performance test of the facility’s enclosed combustion device (flare) to document that the device achieves the 98.0% VOC emission destruction efficiency requirement under the air permit.  On an ongoing basis, Pinnacle conducts semi-annual leak detection tests required under the air permit. This involves visually inspecting each flow indicator and associated alarm for each bypass device, and assessing the concentration of vapors at all potential leak sources via a combustible gas detector.
  • During the growing season, Pinnacle conducts periodic monitoring of the wetland mitigation area from repeatable fixed locations. From each fixed location, the condition of the mitigation basins is assessed and vegetation is documented to the species in each stratum of the wetland area. Pinnacle prepares an annual monitoring report of this information for the ACOE and EPA.
  • Pinnacle created an Operations and Maintenance plan in accordance with the facility’s industrial stormwater permit and established standard operating procedures for conducting inspections for the facility’s industrial stormwater and construction stormwater permits; using these documents, Pinnacle provided onsite training to the staff conducting the inspections.
  • Pinnacle provides ongoing guidance on compliance with the facility’s environmental permits and on plans associated with operating the facility. Pinnacle also provided stormwater training, a requirement of conducting Industrial Stormwater Pollution Prevention Plan (SWPPP) inspections, as well as onsite training on the operation of the facility’s secondary containment equipment.
  • Pinnacle conducts quarterly groundwater monitoring and reporting required under the facility’s CWA 401 permit.
