Assessment report requirements
Proper documentation of the assessment is necessary to meet federal and state requirements and to provide information needed for the abatement process. The assessment report should document the presence of asbestos containing materials and other regulated materials and any features that may contain regulated materials or wastes on the entire parcel or bridge site, not just within the structure.
Guidance on what information is needed in the assessment report for specific types of regulated materials or features that may contain regulated materials/wastes is provided below. The assessment report should be prepared in general conformance with one of the following templates:
The following completed reports are provided as a guide in preparing bridge and building assessment reports:
Asbestos containing materials
The assessment must be conducted by an inspector(s) that is licensed by the Minnesota Department of Health (MDH) and is a Certified Hazardous Material Manager (CHMM). The assessment report must provide the following information for asbestos containing materials (ACM):
- Signature, date and certification number of MDH certified asbestos inspector who performed the assessment;
- Signature, date and certification number of CHMM who performed the assessment;
- Photocopies of the current MDH certified asbestos inspector and CHMM certifications and MDH hard card photo identification for each inspector who performed the assessment;
- Written certification that the assessment was performed in compliance with Minnesota Rules Chapter 4620;
- Location of the structure: street address, parcel number, bridge number, state project number (SP) and trunk highway designation;
- Summary of Action required for the demolition;
- Structure drawing that includes detailed locations of each homogenous area and sampling point of material known or suspected to contain asbestos;
- Condition of each homogenous area of material known to contain asbestos;
- Total quantity of friable, Category I and Category II ACM in each structure;
- Detailed information on location of other regulated materials and any respective sampling completed;
- Spreadsheet identifying the presence or absence of other regulated materials described in the remainder of this document. For materials that are present, provide the total quantity and location in the structure or on the property;
- Laboratory chain of custody forms for any regulated or suspect material sampled. All asbestos samples must be analyzed by a laboratory with one or all of the following active accreditations or successfully participation in one of the following programs:
- Accredited by the National Institute of Science Voluntary Accreditation Program (NIST)
- Accredited by the National Voluntary Laboratory Accreditation Program (NVLAP)
- Successfully Participate in the asbestos bulk analysis program of the American Industrial Hygiene Association (AIHA)
Identify all air conditioning, heat pump, or other refrigeration equipment that contain CFC refrigerant.
Identify location of lead items such as lead bearing plates, lead pipes and any lead bearing materials. Identify location of bridge lead plates.
Identify the number and location of all mercury containing equipment, such as fluorescent, mercury vapor, and HID lighting, electrical switches and other equipment.
Polychlorinated Biphenyls (PCB’s)
Identify the number and location of all light ballasts, transformers, and other electrical equipment that contain PCB’s. Electrical equipment that does not contain PCB’s must be labeled “No PCB’s”. Equipment without labels must be assumed to contain PCB’s and managed and disposed of as PCB waste.
Using professional judgment, identify the type, volume and location of each treated wood (creosote, pentachlorphenol, CCA, etc). If it is not possible to distinguish between the types of treated wood at a site, include a general discussion of the location and volume of treated wood. Do not conduct laboratory analyses of treated wood samples.
Other regulated wastes
- Identify any regulated or hazardous waste left on site and provide the following information:
- Type of waste(s);
- Volume of container(s);
- Number of containers of each type of waste;
- Condition of Container(s).
Other solid wastes
- Identify solid wastes such as appliances and trash;
- Identify the type of appliances present at the site and a general description of any other trash;
- Provide location of solid waste in structures and on the property.
Document presence and location of any features that may contain regulated materials or waste. Examples of these features include, but are not limited to:
- Flammable waste traps
- Underground storage tanks
- Aboveground storage tanks
- Hydraulic hoists
- Trench drains
- Septic systems
