In a rule published July 2, 2002, EPA found the Arizona Department of Environmental Quality’s "Plan for Attainment of the 24-Hour PM10 Standard – Maricopa County PM10 Nonattainment Area" (May 1997), inadequate to achieve attainment of the 24-hour National Ambient Air Quality Standards for particulate matter 10 microns or fewer in aerodynamic diameter (PM10) at the Salt River monitoring site. The 1997 ADEQ SIP revision included attainment and Reasonable Further Progress demonstrations for the 24-hour NAAQS at the Salt River air quality monitoring site of the Maricopa County PM10 Serious Nonattainment Area, as well as at three other monitoring sites in the Phoenix area, - the Maryvale, Gilbert, and West Chandler sites. On August 4, 1997, EPA approved ADEQ’s attainment and RFP demonstrations for the Salt River monitoring area, which showed that the 24-hour PM10 NAAQS would reach attainment in the area by May 1998. Due to continuing violations of the 24-hour PM10 NAAQS at the Salt River air quality monitoring site since May 1998, EPA subsequently required Arizona to submit a revision to correct SIP inadequacies. This document consists of Arizona’s revisions to the state implementation plan for the Maricopa County PM10 Serious Nonattainment Area as described by EPA in its Federal Register notice of disapproval.

The continued growth of the human-built environment in Pima County, Arizona will result in the “incidental take” of species that are listed under the Endangered Species Act. To avoid, minimize, and mitigate impacts to both listed and unlisted species and their habitats, Pima County is submitting this Multi-species Conservation Plan for 44 species that may be impacted as a result of the otherwise lawful activities of Pima County and its development community. The Incidental Take Permit, also called a Section 10 permit, will be for 30 years. This MSCP is part of the required documentation needed to receive an Incidental Take Permit under Section 10(a)(1)(B) of the ESA.

The Multiple Species Conservation Plan will complete the land use planning process in a conflict between competing interests on the question of growth. A path of balance was chosen by advancing the Sonoran Desert Conservation Plan. This second draft will be posted on the website and distributed to interested community and committee members. A public process will be conducted so that during 200t the document can be finalized and submitted to the U.S. Fish and Wildlife Service as part of the application for a federal endangered species permit.

An update to the Flagstaff Regional Plan 2030 (FRP30), to bring its Road Network Illustration (Map 25) into compliance with Arizona Revised Statute requirements and to resolve inconsistencies between Map 25 and parts of the Flagstaff City Code. This update does not alter the intent of FRP30; it is only concerned with correcting errors, removing legal vulnerability, and improving the readability of FRP30.

In this initial (interim) report, 21 different natural resource based outdoor recreational activities are identified. These activities are believed to represent the most popular natural resource based recreational activities in eastern Pima County. Based on the best information available, the document provides an overview and description of each of the noted activities. Information is also provided regarding the primary or preferred locations where the subject activity occurs. Data on participation in the individual activity is included where available. Use patterns, such as seasons when the activity is most prevalent, have been identified and trends related to changes in participation levels are discussed. Finally, issues related to the recreational activity vis-a-vis the goals of the Sonoran Desert Conservation Plan are also presented.

This study from the citizens of the Arivaca community proposes to establish an Arivaca Resource Management Zone, where a atwo level management plan integrates the otherwise fragmented land use and water policies of the various regulatory agencies. The Arivaca watershed contains one of the last remaining cienegas and perennial streams in southern Arizona. These unusual water features exist because the area is still in a state of balance, where annual water consumption is less than the natural recharge replenishing the aquifer during years of average precipitation.
