Flood Damage >> Flood Zone Maps And Asbestos Disposal

As the flooding recedes, communities are moving from the more immediate emergency response to longer term cleanup and recovery. The Department has updated this section of its guidance to reflect the changing nature of the disaster response, and to clarify questions we have received regarding building debris that has the Flood Zone Maps And Asbestos Disposal potential to contain asbestos. 

This guidance only applies to state protocols. This guidance does not alter any federal requirements (e.g., EPA, OSHA) that may also apply with respect to debris cleanup and Flood Zone Maps And Asbestos Disposal worker safety. Please contact the appropriate federal agencies if you have questions regarding the applicability of their regulations. 

For the purposes of this section on Asbestos, the following definitions apply: Tier 1 Building Materials: Any and all building materials that have been displaced or dislodged as a result of the heavy rains and Flood Zone Maps And Asbestos Disposal flooding. This includes, for example debris from demolished homes that may have washed away. 

Tier 2 Building Materials: All other building materials not defined in Tier 1. This includes, for example, building materials from comparatively lesser damaged homes, Flood Zone Maps And Asbestos Disposal such as drywall in a flooded basement. Trigger levels for single family residential dwellings are 50 linear feet on pipes, 32 square feet on other surfaces or the volume equivalent of a 55-gallon drum. 

Trigger levels for public and commercial buildings are 260 linear feet on pipes, 160 square feet on other surfaces or Flood Zone Maps And Asbestos Disposal the volume equivalent of a 55-gallon drum. Tier 1 Building Materials Handling Procedures If asbestos-containing materials are known to be present in flood debris in amounts greater than regulatory trigger levels, they must be removed in accordance with Colorado Air Quality Control Commission Regulation No. 8, Part B. 

If it is not known if asbestos is present in the building materials, any wet material may be handled as non-asbestos flood debris and Flood Zone Maps And Asbestos Disposal disposed of at a permitted landfill. Dry building materials should be wetted and then may be handled as above. A state-issued demolition permit is not required to remove the debris from buildings that have been partially or completely destroyed. 

However, flood debris may contain unknown substances, Flood Zone Maps And Asbestos Disposal including chemicals. People should take care when handling any materials from buildings that either are partially damaged by the floods (i.e., salvageable building materials remaining) or completely destroyed (i.e., only debris remains). 

All debris should be handled in a manner that will minimize potential exposure to both the people handling the material and those in the surrounding area. The heavy rains and flooding will presumably have resulted in debris that is thoroughly wetted, which should minimize dust and Flood Zone Maps And Asbestos Disposal related potential risks from airborne materials during cleanup (including, potentially, asbestos fibers). 

Any material that has dried out should be thoroughly wetted to minimize dust release. The Department will not require flood soaked or Flood Zone Maps And Asbestos Disposal thoroughly wetted materials transported for immediate disposal at the landfills to be wrapped with plastic. Roll-offs and trucks need to be covered to prevent: 1) the materials from drying out and 2) the material from blowing out of the vehicles between the point of pick-up and disposal. 

If the material is thoroughly wetted from flood waters/mud, then potential airborne contaminants should be sufficiently contained for short haul and immediate disposal purposes. In addition, handling flood soaked and muddy materials is hard enough; Flood Zone Maps And Asbestos Disposal adding plastic wrapping could increase personal injury risk and hamper timely and effective cleanup. 

The risks from potential asbestos fibers and other airborne contaminants could increase as the debris dries out. If the material is not thoroughly wetted, then the materials should either be thoroughly wetted or, Flood Zone Maps And Asbestos Disposal if that is not possible, the debris should be packaged inside a 6-mil plastic sheeting liner. This is done to contain the debris as it is transported from the site to the landfill. 

Metal debris must be washed clean of mud/debris prior to recycling. Concrete debris (foundations) removed from a site must be disposed of at an approved landfill. If you wish to recycle this material, Flood Zone Maps And Asbestos Disposal it must be inspected by a certified asbestos building inspector and found to be free of asbestoscontaining materials prior to recycling. 

Tier 2 Building Materials Handling Procedures NOTE: Homeowners doing their own work in their primary residences are exempt from the Tier 2 requirements. However, Flood Zone Maps And Asbestos Disposal homeowners must dispose of asbestos-containing debris in accordance with applicable regulations. All Tier 2 suspect building materials in amounts greater than the trigger levels must be sampled for the presence of asbestos in accordance with Regulation No. 8, Part B 

If asbestos-containing materials are present in amounts greater than the trigger levels, and are going to be removed or impacted by renovation or demolition activities, Flood Zone Maps And Asbestos Disposal those activities must be done in accordance with the Major Spill Response section (III.T.) of Regulation No. 8, Part B. In order to further facilitate the timely and protective cleanup of confirmed asbestos containing materials from this natural disaster.

The Department is providing relief from the following regulatory requirements until further notice: For sampling: The Colorado individual Building Inspector certification requirement is waived, Flood Zone Maps And Asbestos Disposal so long as the individual’s AHERA training is current. The requirement for a Building Inspector to work for a Registered Asbestos Consulting firm is waived. 

The requirement for a laboratory to be registered in Colorado to conduct bulk sample analysis is waived, Flood Zone Maps And Asbestos Disposal but the requirement for the laboratory to be NVLAP-accredited is not waived. For asbestos spill response requirements: Immediate notification to the division by telephone is waived. The 10-day waiting period to begin an abatement project is waived. 

The Colorado individual Worker and Supervisor certification requirements are waived, so long as the individual’s AHERA training is current. The requirement for an abatement company to obtain Colorado certification is waived. Lists of and Flood Zone Maps And Asbestos Disposal contact information for landfills that will accept Tier 2 material can be found on the Air Pollution Control Division’s Asbestos Program
