Air Quality Division: Plans: Agricultural Best Management Practices

The Governor's Agricultural Best Management Practices (AgBMP) Committee was created in 1998 by Arizona Revised Statute (A.R.S.) §49-457 to address PM10 emissions from agricultural activities in the Maricopa County planning area. The Committee researched and adopted best management practices (BMPs) for agricultural activities, and developed an agricultural PM10 general permit under R18-2-610 (definitions) and 611 (practices, permit). The rule was cited in the Maricopa County PM10 State Implementation Plan (SIP). Later, the rule, educational booklet and technical assessment for the BMPs were included in a 2001 Agricultural Best Management Practices SIP.

Due to continued exceedances of the PM10 standard, the Maricopa County PM10 Nonattainment Area was unable to meet attainment of the federal standard by the December 31, 2006, deadline. As a result, the Maricopa Association of Governments (MAG) developed the Five Percent Plan for PM10 for Maricopa County as required under the Clean Air Act Section 189(d). In the first regular session in 2007, the Arizona Legislature revised A.R.S. §49-457 in Section 14 of Senate Bill 1552. The Statute required two BMPs to be implemented per agricultural management category beginning December 31, 2007, and revised the definition of the regulated area for BMPs as the Maricopa County portion of Area A. To reduce PM10 emissions for the contribution from agriculture, the Committee adopted five new BMPs, required two BMP per agricultural category, and extended the area for BMPs to Maricopa County portions of Area A. R18-2-610 and 611 were revised to account for these changes and a revision of the 2001 SIP was completed. The SIP revision, Maricopa County PM10 Serious Nonattainment Area - Agricultural Best Management Practices, is being prepared for submission to U.S. EPA. For detailed BMP information, a public education document entitled Guide to Agricultural PM10 Best Management Practices, Maricopa County, Arizona PM10 Nonattainment Area is available. This document includes an overview of the agricultural PM10 best management practices program, descriptions of the best management practices, suggestions for implementation and a sample record form sample agricultural BMP general permit record that commercial farmers can use to document compliance.

In 2009, the Arizona Legislature passed Senate Bill 1225, revising A.R.S. §49-457. The Statute was revised to add five members to the Committee, one from each of the following areas: beef feedlots, dairies, poultry, swine, and a representative from a county air quality department or agency. The revision also required the AgBMP Program to include management practices for feedlot, dairy, swine, and poultry operations. The bill also contained a provision to include any future PM nonattainment areas. Revisions to the AgBMP Program required a revision to R18-2-610 and 611 by June 30, 2010.
