IMPORTANT TANK SYSTEM UPGRADES & DEADLINES!!!!!!

SECONDARY CONTAINMENT & NON DISCRIMINATING ELECTRONIC SENSORS

DECEMBER 31, 2014

COMM 10.500(5)(d)(e)(f)

Subchapter V — General UST Storage and

Underground Piping

Comm 10.500 General requirements. (1) SECONDARY

CONTAINMENT. (a) General. All new and replacement underground

storage tanks and piping systems shall be provided with

secondary containment and continuous electronic interstitial

monitoring,

(d) All existing pipe connections at the top of the tank and

beneath all freestanding pumps and dispensers, that routinely contain

product shall be placed within secondary containment sumps

by December 31 of the fifth year following February 1, 2009.

(e) All pipe connections at a transition between aboveground

and underground piping that are installed or replaced on or after

February 1, 2009, shall be placed within a secondary containment

sump at the time of installation or replacement.

(f) 1. Secondary containment sumps provided under this subsection

shall have non−discriminating electronic sensors that will

detect liquids in the sump, unless approved otherwise by the

department.

2. Piping that is installed or replaced on or after August 1,

2009, at secondary containment sumps provided under this subsection

may not pass through the bottom of the sump.

3. All electrical conduit and wiring that is installed or replaced

on or after August 1, 2009, at secondary containment sumps provided

under this subsection for dispensers shall pass over the top

of the sump wall rather than through the wall or bottom of the sump.

AUTO SHUT-OFF OVERFILL PROTECTION

FEBRUARY 1, 2011

COMM 10.505(2)(b)

Comm 10.505 Spill and overfill prevention. (1) GENERAL.

(a) Prior to delivery, the operator of the fuel delivery equipment

that is transferring the product shall ensure that the volume

available in the tank is greater than the volume of product to be

transferred to the tank.

(b) The transfer operation shall be monitored constantly by the

operator of the delivery equipment so as to prevent overfilling and

spilling.

(2) EQUIPMENT. All underground storage tank systems,

whether new or existing, shall meet all of the following requirements:

(a) 1. A liquid−tight containment system with a minimum

capacity of 5 gallons shall be provided on top of the tank where

connections are made for product fill piping, except the 5−gallon

minimum does not apply to containment that was installed before

February 1, 2009.

2. The basin shall be equipped with either a drain system that

directs spilled product into the tank, or a mechanism to pump

product out of the basin.

(b) Storage tank overfill prevention equipment shall be provided

that complies with NFPA 30 section 21.7.1.5 and PEI

RP100 chapter 7. Existing tank systems shall comply with this

paragraph within 2 years after February 1, 2009.

Note: NFPA 30 section 21.7.1.5 requires equipment that will (1) automatically

shut off the flow into a tank when the tank is no more than 95 percent full; and (2)

alert the transfer operator when the tank is no more than 90 percent full, by restricting

the flow into the tank or triggering a high−level alarm. Retrofit equipment is available

which complies with these requirements and which can be installed in a tank without

removing pavement. See PEI RP100 section 7.3.2 for description of how the contents

of the delivery hose can be drained into the tank after an automatic shut−off valve

closes.

Comm 10.510 Leak detection requirements.

(1) GENERAL. (a) All new and existing underground tank systems

used to store regulated substances shall be provided with a method

of leak detection that complies with this section and s. Comm

10.515, except as exempted in par. (d).

(b) The method of leak detection shall be approved in accordance

with s. Comm 10.130.

(c) All monitoring equipment used to satisfy the requirements

of this section shall be installed, calibrated, operated and maintained

to perform as originally intended in accordance with the

manufacturer’s instructions and the department’s approval, such

as issued under s. Comm 10.130.

(d) Leak detection is not required for any of the following

tanks:

1. Tanks which have a capacity of less than 1,100 gallons and

which are located on farm premises or at private residences.

2. Tanks storing Class IIIB liquids that are neither petroleum

nor CERCLA−listed products.

(e) If a tank system exhibits a continuing pattern of failing and

then not failing leak detection testing, a precision tightness test

shall be performed within 10 business days in accordance with s.

Comm 10.515 (4), and if a tank system fails to pass that test, the

site shall be assessed for the presence of a release in accordance

with ss. Comm 10.575 to 10.585.
