Code of Massachusetts Regulations › 310 CMR - DEPARTMENT OF ENVIRONMENTAL PROTECTION › Title 310 CMR 30.000 - Hazardous waste › GENERAL PROVISIONS › Section 30.693 - Design and Installation of New Tank Systems or Components

Current through Register 1525, July 5, 2024
(1) Owners or operators of new tank systems
				or components shall obtain and submit to the Department, at the time
				information is submitted to the Department pursuant to
				310 CMR 30.099(6)
				 and
				310 CMR 30.802,
				310 CMR 30.099(7) and
				(8), or 310 CMR 30.850, a written assessment,
				reviewed and certified by an independent, qualified, registered professional
				engineer, in accordance with
				310 CMR 30.009,
				attesting that the tank system has sufficient structural integrity and is
				acceptable for the storing and treating of hazardous waste. The assessment
				shall show that the foundation, structural support, seams, connections and
				pressure controls (if applicable) are adequately designed and that the tank
				system has sufficient structural strength, compatibility with the waste(s) to
				be stored or treated, and corrosion protection to ensure that it shall not
				collapse, rupture, or fail. This assessment be used by the Department, but
				which the Department will not be limited to considering, to determine the
				acceptability of the tank system design, must include, at a minimum, the
				following information:
(a) Design standard(s)
				according to which the tank(s) and/or ancillary equipment are
				constructed.
(b) Hazardous
				characteristics of the waste(s) to be handled.
(c) For new tank systems or components in
				which the external shell of a metal tank or any external metal component of the
				tank system will be in contact with the soil or with water, a determination by
				a corrosion expert of
1. Factors affecting
				the potential for corrosion, including but not limited to:
a. Soil moisture content;
b. Soil pH;
c. Soil sulfides level;
d. Soil resistivity;
e. Structure to soil potential;
f. Influence of nearby underground structures
				(
e.g.
piping);
g.
				Existence of stray electric current;
h. Existing corrosion protection measures
				(
e.g.
coating, cathodic protection); and
2. The type and degree of external corrosion
				protection that are needed to ensure the integrity of the tank system during
				the use of the tank system or component, consisting of one or more of the
				following
a. Corrosion-resistant materials of
				construction such as special alloys, fiberglass reinforced plastic,
etc.
;
b.
				Corrosion-resistant coating (such as epoxy, fiberglass,
etc.
)
				with cathodic protection (
e.g.
impressed current or
				sacrificial anodes); and
c.
				Electrical isolation devices such as insulating joints, flanges,
etc
.
(NOTE - Practices in providing corrosion protection for tank
				  systems are published in the National Association of Corrosion Engineers (NACE)
				  standard,
Recommended Practice (RP-02-85) - Control of External
				  Corrosion on Metallic Buried, Partially Buried, or Submerged Liquid Storage
				  Systems
, and the American Petroleum Institute (API) Publication 1632,
Cathodic Protection of Underground Petroleum Storage Tanks and Piping
				  Systems
.)
(d) For underground tank system components
				that are likely to be adversely affected by vehicular traffic, a determination
				of design or operational measures that will protect the tank system against
				potential damage; and
(e) Design
				considerations to ensure that:
1. Tank
				foundations will maintain the load of a full tank;
2. Tank systems will be anchored to prevent
				flotation or dislodgement where the tank system is placed within ten feet of a
				saturated zone; and
3. Tank systems
				will withstand the effects of a frost heave.
