Guidelines for
Specifying Blastox®
Abrasive Additive for Lead Abatement
When
removing lead based paint or coatings, contractors shall use the Blastox7
abrasive additive blended with a mineral abrasive (such as sand or slag) by the
abrasive supplier. Blastox®
renders the lead non-hazardous, as confirmed by TCLP test results on the spent
abrasive. The spent abrasive can then be properly and safely disposed
of in a local Subtitle D landfill.
The
Blastox®
additive must have the following characteristics:
1.
Particle size
distribution of at least 95% >50 mesh and <12 mesh.
2.
Bulk density of
>80 pounds per cubic foot and <100 pounds per cubic foot.
Hardness >6.0 on the Mohs Scale.
- Must be capable of rendering
leachable lead in the untreated spent abrasive
wastes from up to 100 mg/l to less
than 5.0 mg/l
(non-hazardous) according
to the TCLP.
-
Not be regulated under Section 313 of Emergency Planning and
Community
Right-to-Know Act (EPCRA).
Also know as SARA (Superfund Act and
Reauthorization
Amendments) Title III.
-
Not contain any steel or iron based material, such as but not limited
to grit,
shot, fines or filings due to the EPA
ban on this activity as impermissible
dilution of a hazardous waste (Federal
Register: May 26, 1998, Volume
63,
Number 100, pages 28566 – 28569).
-
Possess a letter from the State Environmental Department, indicating
product can be used without RCRA (or
equivalent) treatment permits.
-
Contain less than .1% soluble salts (e.g., fluorides and chlorides)
All
spent abrasives, residuals or by products of the paint removal process must be
managed in compliance with all applicable local, state and federal regulations.
