310 CMR, § 80.27 - Requirements for Turbine, Intermediate and Dispenser Sumps

(1) Owners and Operators shall operate and maintain turbine, intermediate and dispenser sumps in accordance with 310 CMR 80.27.

(2) Turbine, intermediate and dispenser sumps shall be clean and free of solid and liquid material at all times.

(a) If a sensor or visual observation indicates that there is liquid in the sump, the liquid shall be removed immediately.

(b) If the liquid is a regulated substance, the Owner or Operator shall investigate the source of the regulated substance, shall investigate the path of entry to the sump, and shall make any necessary repairs in accordance with 310 CMR 80.33.

(c) The solid and liquid material that collects in a sump shall be removed, managed and disposed of in accordance with applicable local, state and federal laws and regulations.

(3) All sump sensors shall be placed in accordance with the manufacturer's specifications, or, if no such specifications exist, the sensors shall be placed at the lowest possible location in the sump, where it can feasibly be installed.

(4) All manhole covers shall prevent water infiltration to the sump. All sump covers shall be free of cracks and holes.

(5) All tanks using a submersible pump that do not have a turbine sump shall be inspected every 30 days.

(a) The Owner or Operator shall visually inspect the area around the submersible pump as follows:

1. Visually inspect the submersible pump for release of regulated substance(s); and

2. Visually inspect the submersible pump and other components for signs of corrosion, breakage and wear.

(b) The Owner or Operator shall repair or replace components as necessary in accordance with 310 CMR 80.33; and

(c) The Owner or Operator shall keep records of this inspection and any repairs or replacements to demonstrate compliance with 310 CMR 80.27(5) in accordance with 310 CMR 80.36.

(6) The Owner or Operator shall inspect turbine, intermediate and dispenser sumps, except sumps that only contain a single-walled siphon line with no connections within the sump or sumps that only contain a European suction system or sumps that do not contain any regulated substance piping connections, in accordance with the following and in accordance with 310 CMR 80.35(3) or (4), as applicable:

(a) Single-walled and double-walled sumps without continuous monitoring sensors in the sump shall be inspected every 90 days.

(b) Single-walled and double-walled sumps with correctly installed and operating continuous monitoring sensors in the sump shall be inspected annually.

(7) The Owner or Operator shall conduct an integrity test of turbine, intermediate and dispenser sumps, except sumps listed in 310 CMR 80.27(8), on or before January 2, 2017, on or before October 13, 2021, and once every three years thereafter as follows:

(a) Sumps with properly operating and installed sensors that are not used for interstitial monitoring of piping may be tested hydrostatically to the level that will activate the sensors. The sump passes the integrity test if the sensors are activated when they come in contact with the liquid.

(b) Dispenser sumps with properly operating and installed sensors used for interstitial monitoring of piping and that shuts off the dispenser when activated may be tested hydrostatically to the level that will activate the sensor, if the UST facility is always staffed when the pumps are operational. The sump passes the integrity test if the sensors are activated when they come in contact with the liquid and shut off the dispenser.

(c) Turbine sumps with properly operating and installed sensors that are used for interstitial monitoring of piping and that shuts off the submersible pump when activated may be tested hydrostatically to the level that will activate the sensor. The sump passes the integrity test if the sensors are activated when they come in contact with the liquid and shut off the submersible pump.

(d) Sumps that do not meet the requirements of 310 CMR 80.27(7)(a), (b) or (c) or do not have a sensor shall be integrity tested by vacuum or hydrostatic testing in accordance with PEI RP1200-19.

(8) The following sumps are not subject to the testing requirements in 310 CMR 80.27(7), 80.27(9) or 80.20(54):

(a) Sumps that only contain a single-walled siphon line with no connections within the sump or sumps that do not contain any regulated substance piping connections;

(b) Sumps that only contain a European suction system; and

(c) Double-walled sumps, if the integrity of both walls is monitored every 90 days or annually, as applicable under 310 CMR 80.27(6), by checking vacuum, pressure or liquid interstitial integrity indicators.

1. A sensor in a dry interstice does not meet the requirements of monitoring the integrity of both walls.

2. In order to claim the exemption from testing, the Owner or Operator shall keep documentation showing that the sump is double-walled and that the integrity of both walls is monitored every 90 days or annually, as applicable under 310 CMR 80.27(6), in accordance with 310 CMR 80.36.

(9) If the sump fails a test, the Owner or Operator shall investigate the failure and shall make any necessary repairs in accordance with 310 CMR 80.33.

(a) The Owner or Operator shall keep records of the test and any repairs to demonstrate compliance with 310 CMR 80.27(7) and 310 CMR 80.33 including, but not limited to, the date of the test and the results, in accordance with 310 CMR 80.36.

(b) Turbine, intermediate and dispenser sumps that are repaired, except sumps listed in 310 CMR 80.27(8), shall pass an integrity test in accordance with 310 CMR 80.27(7) prior to commencing operation. The Owner or Operator shall keep records of such tests in accordance with 310 CMR 80.36.

(c) Repairs which do not affect the integrity of a sump to retain liquid including, but not limited to, a sump lid and gasket, do not require an integrity test prior to commencing service.
