Draft New and Revised General Construction Permits
Crushing, Sand and Gravel (GCP-2)
Asphalt Plants (GCP-3)
Concrete Batch Plants (GCP-5)
This web page will be updated regularly to contain information
about the ongoing activities for issuance of a General Construction Permit (GCP)
for concrete batch plant operations, and for posting the proposed revised
versions of the existing crushing, sand and gravel, and asphalt plants GCPs for
public comment. All documents listed below are in PDF (Adobe
Acrobat) format unless otherwise noted.
The Crushing, Sand and Gravel (GCP-2) permit and Asphalt Plant
(GCP-3) permit were revised to ensure collocation compatibility with the new
Concrete Batch Plant (GCP-5) permit.
All three draft GCPs have been revised as of
June 22, 2006. The revisions come as a result of a public
meeting held on February 22, 2006 and a March 16, 2006 meeting with the Board of
the New Mexico Readymix Concrete Association. Additional public meetings
were held May 11 through May 22, 2006, in Las Cruces, Farmington, Las Vegas, and
Roswell. Written comments were also
considered.
Each issue was evaluated by the Department. Where accommodation
was possible, requirements were clarified, reworded, changed, or removed.

Concrete Batch Plants (GCP-5) Background:
In October of 2001, the EPA issued a revised edition of the AP-42 emission
factors. The revised uncontrolled emission factors from Section 11.12, Concrete
Batching, make it probable that few, if any, concrete batch plants now qualify
to operate under a Notice of Intent. Using these new emission factors,
state regulation (20.2.72 NMAC) requires that both new and existing concrete
batch plants (CBP) obtain a regular NSR permit.
In order to facilitate this permitting process, the Air Quality Bureau has
developed a draft General Construction Permit (GCP) specifically for
Concrete Batch Plants (GCP-5). The GCP alternative should provide
several advantages over a regular permit including faster turnaround time and
lower cost.
