Conn. Agencies Regs. § 19a-333-4 - Sampling

Current through March 4, 2022

(a) Surfacing material. An accredited inspector shall collect bulk samples of surfacing material, in a statistically random manner which is representative of the homogeneous area of friable surfacing material that is not assumed to be ACM, and shall collect such samples as follows:
(1) at least three (3) bulk samples from each homogeneous area that is one-thousand (1,000) square feet or less, except as provided in subsection (d) of section 19a-333-5 of the regulations of Connecticut State Agencies;
(2) at least five (5) bulk samples shall be collected from each homogeneous area that is greater than one-thousand (1,000) square feet but less than or equal to five-thousand (5,000) square feet, except as provided in subsection (d) of section 19a-333-5 of the regulations of Connecticut State Agencies;
(3) at least seven (7) bulk samples shall be collected from each homogeneous area that is greater than five-thousand (5,000) square feet, except as provided in subsection (d) of section 19a-333-5 of the regulations of Connecticut State Agencies.
(b) Thermal system insulation
(1) Except as provided in subdivisions (2) through (4) of this subsection and subsection (c) of section 19a-333-5 of the regulations of Connecticut State Agencies, an accredited inspector shall collect, in a randomly distributed manner, at least three (3) bulk samples from each homogeneous area of thermal system insulation that is not assumed to be ACM.
(2) An accredited inspector shall collect at least one (1) bulk sample from each homogeneous area of patched thermal system insulation that is not assumed to be ACM if the patched section is less than six (6) linear or square feet.
(3) In a manner sufficient to determine whether the material is ACM or not ACM, an accredited inspector shall collect bulk samples from each insulated mechanical system that is not assumed to be ACM where cement or plaster is used on fittings such as tees, elbows, or valves, except as provided under subsection (d) of section 19a-333-5 of the regulations of Connecticut State Agencies.
(4) Bulk samples are not required to be collected from any homogeneous area where the accredited inspector has determined that the thermal system insulation is fiberglass, foam glass, rubber, or other non-ACBM.
(c) Miscellaneous material. In a manner sufficient to determine whether material is ACM or not ACM, an accredited inspector shall collect bulk samples from each homogeneous area of friable miscellaneous material that is not assumed to be ACM.
(d) Nonfriable suspected ACBM. If any homogeneous area of nonfriable suspected ACBM is not assumed to be ACM, then an accredited inspector shall collect, in a manner sufficient to determine whether the material is ACM or not ACM, bulk samples from the homogeneous area of nonfriable suspected ACBM that is not assumed to be ACM.
