1.22 Required Asbestos Abatement and Management Procedures:

These steps are in accordance with Air Force Instruction, EPA, and MDEQ. OSHA governs all worker safety and must be complied with by contractors and subcontractors. These requirements are summarized in the Keesler Air Force Base Asbestos Operations and Management Plan. Please reference the Plan.

These steps are required by all personnel or contractors doing work on Keesler Air Force Base.

• Once it is determined by the Asbestos POC that asbestos is present, the following actions are required (Only the APOC and Bioenvironmental are certified to make that determination).

NO ABATEMENT WORK IS TO BEGIN WITHOUT WRITTEN APPROVAL FROM THE

APOC.

A Mississippi State certified asbestos abatement contractor must be used to conduct the abatement. Please note that non-friable asbestos can easily be made friable and become regulated.

The following documents must be submitted to the Asbestos POC and approved in writing before abatement can begin:

• 10 Day MDEQ notification and return acknowledgment letter

• Asbestos Hazard Abatement Plan (to be certified by a Mississippi Certified Management Planner and or Certified Industrial Hygienist )

• Asbestos Work Plan (scope of work, removal procedures, worker protection, air monitoring, disposal location, containment procedures)

• MDEQ Asbestos Abatement Certification for the Company

• Supervisors qualifications and state certification

• CURRENT State Certifications (applications will not be accepted) for all individuals working on site

• Respirator fit test for all individuals

• Physicals for all individuals

Once the submittals are approved in writing, the following actions are required.

• The contractor is required to set up their containment areas, negative air machine, and critical barriers and obtain approval from our Asbestos POC to begin work.

• The Asbestos POC routinely checks the abatement work to ensure that the containment area and critical barriers are secure, that the workers are wearing the appropriate personal protective equipment that the asbestos containing material is being bagged appropriately, and that air monitoring is being conducted on the workers and outside the abatement area. This also includes reviewing the daily log maintained on site to assure that no uncertified individuals are performing abatement work.

• Upon completion of the abatement work, the contractor contacts the Asbestos POC to conduct a walk-through of the area and approve that all abatement has been completed and that the area has been cleaned of asbestos fibers. This will require at least a 24-hour period. Please reference cleaning procedures in the Asbestos Management and Operations Plan.

• Air sampling results are required to be taken and submitted for approval by the APOC before the containment area, negative air machine, and critical barriers can be removed.

• All asbestos waste must be handled and disposed of in accordance with State law. The APOC must review the waste prior to leaving the base and the manifest will be signed by a designated Keesler government representative. Contractors will not sign manifests for ACM.

After the abatement has been complete, and approved by the APOC, the contractor shall submit the following items in a post-job submittal to be maintained in the Asbestos Abatement Files.

Air sampling results

Daily report logs

Daily worker sign in/out sheets

Waste manifest (Generator Copy)

The contractor shall notify Tom Minton, CSC/CEV, at 228-377-3004 before start of project.

2. Paint contractor must collect paint chips in their own clean buckets, and then have CSC/CEV dispose (if contract requires CEV dispose).

The contractor must use water or amended water when scraping or chipping. All members of the contractor’s work force must wear protective clothing, under OSHA rules, and booties for hazardous waste which will be worn on t the poly, and all such PPE shall be stored on the protective plastic, not removed until complete, and shall be disposed of in an approved manner. Minimum respiratory protection for any OSHA “trigger task” such as scraping, manual sanding, demolition, heat gun and power tool cleaning is a half-mask APR with HEPA filter that is at least 99.97 percent efficient (i.e. P100). APR fit tests evidence must be provided. Other circumstances may warrant higher protection.

3. The contractor shall meet with CSC/CEV just prior to beginning project to discuss protective measures, best management practices (BMP’s), any landfill disposal, and maintenance of chips and their collection (until they are turned over to CSC/CEV, if contract specifies CEV dispose).

4. Any buildings with lead-based paint, if bead blasted to remove old paint, shall have a contractor with proper training. Any exterior paint removal by sanding, grinding, high pressure washing, etc., must be completed by certified lead-based paint workers and supervisor, and also certified by the State of Mississippi, Air Division-Lead Section.

5. The contractor, under OSHA rules, must conduct contract under lead paint rules (including notification to CSC/CEV and MDEQ, as well, if job is an abatement), appropriate prior training and possible personal monitors on workers until it is demonstrated there is no airborne lead risk.

6. Full abatements such as removal of paint to substrate, encapsulation, enclosure, removal and/or removal/replacement of components, or soil removal/covering require fully trained/ certified companies, workers, and supervisors, as well as six (6) prior work-days notification to MDEQ. CSC/CEV must be provided copies of and verify the 6-day notice, all Mississippi state Certifications, copies of medical examinations, and copies of respirator fit tests before beginning any job.
