3. Will the cleaning follow ths cleaning of the
exterior which is supposed to be done by the EPA? We
understand that it is essential that the cleaning of the
exterior, including the air shafts, ba completed before
interior cleaning begins.
4. Will DEP take responsibility for cleaning ths
tenants' personal property which is in their apartments?
5. What standard will be used to determine that
the apartment Is free of asbestos? We are concerned that the
DEP employ a health based standard, rather than the ahera
standard.
6, What sampling methods will be used? It is
critical to us that aggressive tasting be done.
7. Will the DEP also test for fine particulates
{PM2.5), lead and dioxin, and if so, at what standard? We
have been advised that testing for these substances is
critical before reoccupancy, and that the following standards
should be used:
a. PM2.5 - 40 micrograms/m3;
b. Lead - 40 micrograms/ft2;
c. Dioxin- 2 nanograms /m3;
d. Mercury - as required by federal law.
8. Mill the DEP remediate mold? There is a
significant mold problem in several apartments in the
building.
9, Will DEP clean the common areas of the
building, including the air shafts, elevator shaft, heating
ducts and basement? We understand that the cleaning of the
heating ducts should be done by firms certified by the
National Air Duct Cleaners Association. Please confirm that
this will be done, as this is, of course, critical to a
thorough cleaning process.
