Current through Register Vol. 50, No. 8, August 20, 2024

Section III-2717 - Response Actions

A. The local education agency or the state government shall select and implement in a timely manner the appropriate response actions in this Section consistent with the assessment conducted in LAC 33:III.2713. The response actions selected shall be sufficient to protect human health and the environment. The local education agency or the state government may then select, from the response actions which protect human health and the environment, that action which is the least burdensome method. Nothing in this Section shall be construed to prohibit removal of ACBM from a school or state building at any time, should removal be the preferred response action of the local education agency or the state government. If any damaged or significantly damaged thermal system insulation, friable surfacing ACM or miscellaneous ACM is present, the local education agency or the state government shall:

1. immediately isolate the area with the damaged or significantly damaged thermal system insulation, and restrict access to protect human health and the environment until the response action is completed; and

2. perform any response actions in accordance with appropriate requirements as provided in LAC 33:III.5151.

B. If damaged or significantly damaged thermal system insulation ACM is present in a building, the local education agency or the state government shall:

1. repair the damaged area;

2. remove the damaged material if it is not feasible, due to technological factors, to repair the damage; and

3. maintain all thermal system insulation ACM and its covering in an intact state and undamaged condition.

C. Selection of Response Action for Damaged ACM

1. If damaged friable surfacing ACM or damaged friable miscellaneous ACM or damaged floor covering that contains ACM is present in a school or state building, the local education agency, or the state government shall select from among the following response actions: encapsulation, enclosure, removal, or repair of the damaged material.

2. In selecting the response action from among those that meet the definition in LAC 33:III.2703 and, the local education agency or the state government shall determine which of these response actions protects human health and the environment. For purposes of determining which of these response actions are the least burdensome, the local education agency or the state government may then consider local circumstances, including occupancy and use patterns within the school or state building, and its economic concerns, including short- and long-term costs.

D. Selection of Response Action for Significantly Damaged ACM

1. If significantly damaged friable surfacing ACM or significantly damaged friable miscellaneous ACM or significantly damaged floor coverings as defined in LAC 33:III.2703.A that contain ACM is present in a school or state building, the local education agency or the state government shall remove the material in the functional space, or depending upon whether enclosure or encapsulation would be sufficient to protect human health and the environment, enclose or encapsulate.

E. If any friable surfacing ACM, thermal system insulation ACM friable miscellaneous ACM, or floor coverings that contain ACM that has potential for damage is present in a building, the local education agency or the state government shall at least implement an operations and maintenance (O and M) program, as described under LAC 33:III.2719.

F. If any friable surfacing ACM, thermal system insulation ACM, friable miscellaneous ACM, or any floor covering that contains ACM that has potential for significant damage is present in a building, the local education agency or the state government shall:

1. implement an O and M program, as described under LAC 33:III.2719;

2. institute preventive measures appropriate to eliminate the reasonable likelihood that the ACM or its covering will become significantly damaged, deteriorated, or delaminated; and

3. remove the material as soon as possible if appropriate preventive measures cannot be effectively implemented, unless other response actions are determined to protect human health and the environment. Immediately isolate the area and restrict access if necessary to avoid an imminent and substantial endangerment to human health or the environment.

G. A response action related to removal of floor coverings that contain ACM in a school or state building shall follow the requirements of this Section and those requirements related to renovations in LAC 33:III.5151.F and J.

H. Response actions including removal, encapsulation, enclosure, or repair, other than SSSD repairs, shall be designed, supervised and conducted by persons accredited to design, supervise and conduct response actions.

I. Local education agencies and the state government shall comply with either the OSHA asbestos worker protection for general industry at 29 CFR 1910.1001 or the asbestos construction standard at 29 CFR 1926.1101, whichever is applicable.

J. Completion of Response Actions

1. At the conclusion of any action to remove, encapsulate, or enclose ACBM or material assumed to be ACBM, a person designated by the local education agency or the state government, shall visually inspect each functional space where such action was conducted to determine whether the action has been properly completed.

2. The following requirements apply to collection and analysis of air samples.

a. A person designated by the local education agency or the state government shall collect air samples using aggressive sampling as described in EPA regulations contained in 40 CFR part 763, subpart E, appendix A to monitor air for clearance after each removal, encapsulation, and enclosure project involving ACBM, except for SSSD projects.

b. Local education agencies and the state government shall have air samples collected under this Section analyzed for asbestos using laboratories accredited by the Department of Environmental Quality according to LAC 33:I, Subpart 3, Chapters 45-59, to conduct such analysis using phase contrast microscopy (PCM) and transmission electron microscopy (TEM) equipped with an energy dispersive x-ray analysis system or, under circumstances permitted in this Section.

3. Except as provided in Paragraph J.4, 5, or 7 of this Section, an action to remove, encapsulate, or enclose ACBM shall be considered complete when the average concentration of asbestos of five air samples collected within the affected functional space and analyzed by the TEM method contained in EPA regulations 40 CFR part 763, subpart E, appendix A is not statistically significantly different, as determined by the Z-test calculation found in EPA regulations 40 CFR part 763, subpart E, appendix A from the average asbestos concentration of five air samples collected at the same time outside the affected functional space and analyzed in the same manner, and the average asbestos concentration of the three field blanks described in EPA regulations, 40 CFR part 763, subpart E, appendix A is below the filter background level of 70 structures per square millimeter (70 s/mm²).

4. An action may also be considered complete if the volume of air drawn for each of the five samples collected within the affected functional space is equal to or greater than 1,199 L of air for a 25-mm filter or equal to or greater than 2,799 L of air for a 37-mm filter, and the average concentration of asbestos as analyzed by the TEM method in EPA regulations, 40 CFR part 763, subpart E, appendix A for the five air samples does not exceed the filter background level of 70 structures per square millimeter (70 s/mm²). If the average concentration of asbestos of the five air samples within the affected functional space exceeds 70 s/mm², or if the volume of air in each of the samples is less than 1,199 L of air for a 25-mm filter or less than 2,799 L of air for a 37-mm filter, the action shall be considered complete only when the requirements of Paragraph J.3 or 5 of this Section are met.

5. At any time, a local education agency or the state government may analyze air monitoring samples collected for clearance purposes by phase contrast microscopy (PCM) to confirm completion of removal, encapsulation, or enclosure of ACBM that is greater than SSSD and less than or equal to 64 square feet or 60 linear feet. The action shall be considered complete when the results of samples collected in the affected functional space and analyzed by PCM using the National Institute for Occupational Safety and Health (NIOSH) Method 7400 entitled "Fibers" published in the NIOSH Manual of Analytical Methods, 3rd Edition, Second Supplement, August 1987, show that the concentration of fibers for each of the five samples is less than or equal to a limit of quantitation for PCM (0.01 fibers per cubic centimeter [0.01 f/cm³] of air). A description of the method is available at the Office of the Federal Register information center. The method is incorporated as it exists on the effective date of this Rule, and a notice of any change to the method will be published in the Louisiana Register.

6. To determine the amount of ACM affected under Paragraph J.5 of this Section, the local education agency or the state government shall add the total square or linear footage of ACM within the containment barriers used to isolate the functional space for the action to remove, encapsulate, or enclose the ACM. Contiguous portions of material subject to such action conducted concurrently or at approximately the same time within the same school or state building shall not be separated to qualify under Paragraph J.5 of this Section.

7. In the case of a demolition of a school or state building where occupants will not reenter the building, clearance sampling is not required.

K. Response actions in a school building, state building, or public and commercial building including removal, encapsulation, enclosure, or repair, other than SSSD shall be designed, supervised, and conducted by persons accredited to perform such activities.
