I see from previous comments that the amount of lead present on a site might not matter, however, I thought it wouldn't hurt to pose this question, just in case.
My project has lead contamination, though not from paint. The site has a building being demolished that formerly held a firing range for many decades. The lead is from the artillery used and discarded there. I would believe that this lead content would be much higher than that from paint, though I am not certain at this time.
Would this approach be a worthy effort to make as a brownfield alternative compliance path? Any ideas for what kind of supporting documentation (outside of the brownfield designation, records of testing conducted on the site, and records of the remediation performed) may be of use?
