ResponseSpill NEWMONT .. ility& External Relations 40 CFR(1) Requirement* Location in Plan (you may not use flapper-type valves). 112.8(b)(3) For undiked areas with a potential for discharge, design the drainage systems to flow into a pond, lagoon,etc.,designed to retain the oil or return it to the Facility; Section 4.1.2 and locate catchment basins outside of areas subject to periodic flooding. 112.8(b)(4) For a Facility not engineered as in (b)(3)above, equip the final discharge of all ditches inside the Facility with a diversion system that would, in the event of an Section 4.1.2 uncontrolled discharge, retain the oil in the Facility. 112.8(b)(5) Where drainage waters are treated in more than one treatment unit and such treatment is continuous, and pump transfer is needed, provide two "lift" pumps, with at least one permanently installed. Design the Facility drainage systems to Section 4.1.9 prevent a discharge in case there is an equipment failure or human error at the Facility. 112.8(c)(1) Only use a container where the material and method of construction are compatible with the stored material and the conditions of storage,such as temperature and 4.1.1 pressure. 112.8(c)(2) Provide all container installations with secondary containment for the entire installation,the containment to have a capacity of the largest single container, and 4.1.2 sufficient freeboard to contain precipitation;and ensure that diked areas(walls and floors)are sufficiently impervious to contain discharged oil. 112.8(c)(3) Prevent the discharge of uncontaminated precipitation from diked container areas directly to the storm sewer,etc., (i.e., bypassing any treatment system)unless: (i) the bypass valve to the treatment system is sealed closed; Section 4.1.3 (ii) the rainwater drainage is inspected to avoid a discharge of oil; Section 4.1.3 (iii) the bypass valve to the treatment system is opened and resealed under Section 4.1.3 responsible supervision;and (iv) records are maintained of such events. Appendix F 112.8(c)(4) Protect any completely buried metallic storage tanks installed after January 10, 1974, by coating or cathodic protection;and regularly leak test those tanks. Section 4.1.5 112.8(c)(5) Protect the buried portion of any partially buried metallic storage tanks by coating or cathodic protection,or do not use the tanks. Section 4.1.5 112.8(c)(6) Test aboveground containers at some suitable frequency for integrity using visual inspections and another system of non-destructive testing.Also: inspect the supports and foundations of the containers; keep records of the comparisons of the tests/inspections;and Section 4.1.6 frequently inspect the outside of all containers visually for deterioration, discharges,or accumulation of oil inside their dikes. 112.8(c)(7) Control leakage of internal heating coils by monitoring the steam return or exhaust lines for oil,or pass the lines through a separation or retention system. Section 4.1.7 112.8(c)(8) Engineer or update each container installation in accordance with good engineering practice to avoid discharges, providing at least one of the following: (i) high liquid level alarms with an audible or visual signal; (ii) automatic high liquid level pump cut-off devices; Section 4.1 (iii) a direct signal between the container gauge and pumping station;or (iv) a fast response system to detect oil level of each storage container with a person present to monitor gauges.Also: (v) regularly test liquid level sensing devices. 112.8(c)(9) Observe the effluent treatment plant frequently enough to detect upsets that could Section 4.1.9 - - - ------ --------- - --- -------- -- - ----- - ------- .. _._ _.. - -- -- ----- -------- --- Department THIS DOCUMENT IS UNCONTROLLED IN HARDCOPY FORMAT Doc Id:NA-CCV-SER-PLAN- 1930
