I want to modify the roof of my house. Do I need to re-do the survey?
No, as long as there has been no change in the material(s) or in the condition of the material(s) previously surveyed.
If I am using a survey that was conducted 10 years ago that only had one (1) sample results, do I need to update my survey to include three (3) sample results?
Previous surveys that show that only one sample was examined and that the test results for the sample show that the material contains more than 1% asbestos are still valid as long as they are revised to include a statement that the Certified Asbestos Consultant (CAC) or Certified Site Surveillance Technician (CSST) assumes, based on prior testing, that the material is ACM subject to Rule 1403. Similarly, previous surveys where a consultant has assumed or presumed suspect materials to be ACM regardless of the number of samples collected or examined are similarly still valid. Previous surveys that show that fewer than the required three (3) samples were collected, and that the test results show 1% or less asbestos may not meet current Rule 1403 requirements.
Subclause (d)(1)(B)(v)(I) of Rule 1403 does not require a notification to be updated when the quantity of affected asbestos-containing material decreases or increases by less than 20%. Will this apply to ACM that was not initiallyincluded in the survey, provided that the clean‐up procedure is not changed? Do I need to revise the survey and/or submit another notification when I find a material that was not included in the first survey?
All materials that may be disturbed during a renovation or demolition must be surveyed for condition and the presence of asbestos. If new materials are found that were not surveyed, then those new materials must be surveyed. If those materials are determined to be Asbestos-Containing Material (ACM) and will be disturbed during the renovation or removed prior to demolition, then the Notification must be revised to include these materials
