Asbestos Demolition, Renovation and Manufacturing
Section 303 Demolition, Renovation, and Removal
11-2-303 Demolition, Renovation, and Removal: To prevent emissions from asbestos-containing material, a person responsible for scheduled, nonscheduled, or emergency demolition, renovation, or removal of any building elements containing any amount of RACM shall use the procedures specified in subsections 303.1 through 303.13. This shall not apply to maintenance or decontamination procedures where no removal takes place.
303.1 Wetting Method: All exposed RACM shall be adequately wetted and kept wet during cutting, stripping, demolition, renovation, removal and handling operations both inside and outside of a building, except when the methods specified in subsections 11-2-303.2 and 11-2-303.4 are used. Wetting requirements are suspended when the temperature at the point of wetting is below Zero degrees C (32 degrees F) in which case elements of RACM shall be removed in units or in sections to the maximum extent possible.
303.2 Exhaust and Collection Method: In lieu of wetting, a local HEPA exhaust, ventilation, and collection system designed and operated to capture the emissions from RACM and prevent any visible emissions to the outside air may be used during 1) stripping of any element that has been removed as a unit or in sections, in accordance with subsection 11-2-303.4; 2) to prevent emissions of particulate asbestos-containing material to the outside air when damage to equipment resulting from wetting would be unavoidable; 3) shotblasting of mastic. Approval for dry removal of RACM must be received from the APCO; requests for approval of dry removal must be in writing and meet the notification provisions of Section 11-2-401.
303.3 Scheduling of Demolition Activities: RACM shall be removed prior to demolition, or other operations that would either break up, or preclude access to the RACM for subsequent removal. Removal of RACM which is encased in concrete or other similar structural material is not required prior to demolition, but such material shall be adequately wetted whenever exposed during demolition or renovation and disposed of as RACM as required in Section 304.
303.4 Removal in Units: Elements that have RACM may be removed at any time in units or sections so long as the exposed RACM during cutting or disjointing is adequately wetted or encapsulated to prevent emissions of particulate asbestos material. Such sections if elevated shall be carefully lowered to ground level, where they are to be abated in accordance with Section 11-2-303.1 and/or subsection 11-2-303.2.
303.5 Removal By Chute or Container: All RACM not removed in units or sections shall be adequately wetted and kept wet in accordance with subsection 11-2-303.1, and transported to the ground in leak-tight chutes or containers, utilizing negative air and HEPA equipment.
303.6 Containment Requirement: Any building, structure, room, facility or installation from which RACM is being stripped or removed shall be isolated by physical barriers from the outside air to the extent feasible as determined by the APCO. Such barriers shall include transparent viewing ports which shall be in place prior to the commencement of the removal of the RACM and which allow observation of all stripping and removal of RACM from outside the barrier. The negative air pressure inside the isolated work area shall be maintained at a pressure differential relative to adjacent, non-isolated areas to the extent feasible. The negative air pressure ventilation equipment shall be operated continuously from the establishment of isolation barriers through final clean-up of the work area following stripping of removal of RACM. Any such local exhaust ventilation system shall filter the air from the isolated area with a HEPA filter or equivalent, prior to exhausting. The provisions of this subsection shall not apply to a removal done entirely by the glovebag method, provided the bag is evacuated with a HEPA filter vacuum prior to removal from the element being stripped; a removal using a mini-enclosure designed and operated according to current OSHA standards; (ed. note: Fed OSHA Construction Standard changed to 29 CFR 1926.1101; and Cal/OSHA has amended Title 8 Section 1529), a removal of one square foot or less done in accordance with subsection 11-2-303.1 and using a local HEPA exhaust, ventilation and collection system, or a removal using any other engineering control technique approved by the APCO. The requirement to maintain negative air pressure shall not apply to outdoor pipeways at industrial facilities; however these jobs shall be contained by plastic barriers to the extent feasible to prevent visible emissions of RACM.
303.7 Clean Work Site Requirement: All friable asbestos-containing waste material related to a specific demolition, renovation or removal, including pre-existing debris, shall be handled in accordance with the provisions of Sections 11-2-303 and 11-2-304.
303.8 Surveys: Except for ordered demolitions, prior to commencement of any demolition or renovation, the owner or operator shall thoroughly survey the affected structure or portion thereof for the presence of asbestos-containing material, including Category I and Category II nonfriable asbestos-containing material.. The survey shall be performed by a person who is certified by the Division of Occupational Safety and Health, and who has taken and passed an EPA-approved Building Inspector course and who conforms to the procedures outlined in the course. The survey shall include sampling and the results of laboratory analysis of the asbestos content of all suspected asbestos-containing materials. This survey shall be made available, upon request by the APCO, prior to the commencement of any RACM removal or any demolition. This subsection shall not apply if the owner or operator asserts that the material to be renovated is RACM and will be handled in accordance with the provisions of Sections 11-2-303, 304 and 401. The requirement for certification by the Division of Occupational Safety and Health shall not apply to in-house health professionals within a specific non-asbestos related company who perform occasional surveys only for that company as part of their regular job responsibilities.
303.8.1 When a structure, or portion thereof, is demolished under an ordered demolition, the survey must be done prior to, during, or after the demolition but prior to loading or removal of any demolition debris. If the debris contains regulated asbestos-containing material, all of the debris shall be treated as asbestos-containing waste material pursuant to Section 11-2-304.
303.8.2 For renovation or demolition of residential buildings having four or fewer dwelling units, a survey is not required. A sample and test of the material will be required only when any of the following will be removed or disturbed: heating, ventilation, air conditioning ducting and systems; acoustic ceiling material or acoustic plaster; textured or skim coated wall surfaces, cement siding or stucco, or resilient flooring. Where the material if found to contain greater than 1 percent asbestos and is friable, the material must be handled in accordance with Section 11-2-303.
303.9 On-Site Representative: No RACM shall be stripped or removed unless at least one on-site representative, such as a foreman or management-level person or other authorized representative, certifies that he or she is familiar with the provisions of this rule as it pertains to demolition and renovation and the means of compliance therewith, and is present during all stripping and removing of RACM. The required training shall include: applicability of the regulation, notifications, procedures, material identification, and control procedures for removals, including adequate wetting, local exhaust ventilation and HEPA filtration, negative pressure enclosures, glove-bag procedures, waste disposal work practices, and reporting and record keeping requirements. Evidence that the required training has been completed shall be posted on-site and made available for inspection by the APCO. This subsection shall not apply to RACM stripped or removed from an owner-occupied single-family dwelling by the owner.
303.10 RACM Discovered After Demolition: If RACM is not discovered until after demolition begins and as a result of the demolition cannot be safely removed, the asbestos-contaminated debris shall be treated as asbestos-containing waste material and kept adequately wet at all times until disposed of according tot he provisions of Section 11-2-304. Immediately after the RACM is discovered the owner or operator shall comply with the provisions of subsections 11-2-303.1, 303.6 and 401.3.
303.11 Ordered Demolition: The owner or operator of any demolition of any building or other stationary structure pursuant to an order of an authorized representative of a state or local government agency, issued because that building is structurally unsound and in danger of imminent collapse, or has been declared a public nuisance, shall comply with the survey requiremens of subsection 11-2-030.8, the wetting requirements of subsection 11-2-303.1 and the disposal requirements of Section 11-2-304. Fire training is not exempted from this Section.
303.12 Intentional Burning: If demolition is accomplished by intentional burning, all RACM, including Category I and Category II nonfriable asbestos-containing material shall be removed in accordance with Section 11-2-303, before burning.
303.13 Emergency Renovation: An emergency renovation shall be approved by the APCO prior to the initiation of work and shall apply only to the abatement of the immediate hazard.
