and protocols set forth by the Professional Engineer for this SPCC Plan. CRDM visual & continuous electronic monitoring configuration precludes the scheduling of periodic integrity tests until 2028, unless prescribed by the local CUPA. Any leakage from the primary container into the integral secondary would be detected through continuous electronic monitoring. Visual inspections, on a daily basis, could detect leaks from the system itself, if leaking from the system. Tanks are raised above the ground for easy visual inspection. If 55 gal. drums are used onsite for liquid petroleum storage, they must have secondary containment. Corrosion poses minimal risk of failure since drums are single-use and would remain on site for a relatively short period of time (less than one year). The drum storage area, if any, to be inspected monthly. This is in accordance with accepted industry practice for drum storage and provides an effective means of verifying container integrity, as noted by EPA in the preamble to the SPCC rule at 67 FR 47120. 3.9 Spill Reporting (40 CFR 112.7(a)(4)) The discharge notification form included in Appendix I will be completed upon immediate detection of a discharge and prior to reporting a spill to the proper notification contacts. 3.10 Potential Discharge Volumes & Direction of Flow The potential discharge volumes and the directions of flows are outlined and presented above in Table 3-2, along with the specific secondary containment for that vessel. It is also noted herein that any product which would reach the ground outside of its secondary containment structure would still be contained via the system of the concrete enclosure limited containment capabilities. 3.11 Containment and Diversionary Structures (40 CFR 112.7(c)) Methods of secondary containment at this facility include a combination of structures (e.g., enclosure, berm, topography), drainage systems (topography rain water runoff), and land- based spill response (e.g., drain covers, sorbents) to prevent oil from reaching navigable waters and adjoining shorelines: < For bulk storage containers (refer to Section 4.2.1 of this Plan): < In transfer areas and other parts of the facility where a discharge could occur: < Drip pans. Fill ports for all ASTs are equipped with drip pans/pails to contain small leaks from the piping/hose connections < Sorbent material. Spill cleanup kits that include absorbent material, and other portable barriers are located in the spill kit trailer midway at the East side of easternmost boat storage structure. The spill kit may include other sorbent material, including booms, and other portable barriers are stored in the storage room close to the large ASTs to allow for quick deployment in the event of a discharge during loading/unloading activities or any other accidental discharge. Materials beyond absorbents are recommended, 27
