Data Collection Report - Flood Control District of Maricopa County

E. Hazardous Waste InventoryThe effort described in this section of the data collection report brieflydescribes currently available environmental records, with regards toenvironmental and toxic waste categories, within the project area. Thissection of the report was completed by Environmental Data Resources,Inc. (EDR), a vendor specializing in the maintenance of a variety ofdatabases designed specifically for inventorying hazardous and toxicwaste sites. The sole purpose of this summary of data is to provide aplanning tool for use during the Durango ADMP alternative analysisprocess.MethodologyA search of available environmental records was conducted by EDR on12-28-99. The area of the subject property for which the search wascompleted was described to EDR as the Durango Area Drainage MasterPlan (ADMP) study area, Phoenix, Arizona. The environmental recordsearch conducted by EDR consisted of searching 24 electronicenvironmental databases, which they regularly update. All of thesedatabases and the search results for the project area are discussed below.Summaries of the results of the database search are also presented inTable V-6.This database search documented 405 different hazardous waste siteswithin the Durango ADMP area. Many of these hazardous waste sitesappeared in several databases and the same address often had more thanone hazardous waste “microsite” present. This was particularly true forthose businesses and facilities that have multiple underground and/orabove ground storage tanks.Every hazardous waste source, its address, and all other specificinformation provided by EDR are available in an electronic format. Acondensed version of this database is available both in the Appendixand in the electronic format. An index to the codes used in thesehazardous materials inventory tables is available both in the Appendixand in the electronic format. Since there were over 1,000 differenthazardous waste sources identified within the Durango ADMP area, theyare not listed individually in this summary. However, maps of theDurango ADMP area that do identify every hazardous waste site in theproject area are presented in this report (Figures V-5 and V-6).The maps of the Durango ADMP area were reviewed in an attempt tocreate more “user friendly” maps with less clutter of hazardous wastesites. However, even after removing 13 of the less serious types of sites,the number of sites on the modified maps was only 25 fewer than on theoriginal maps. Therefore, the attempt to create less cluttered maps wassubsequently abandoned. The site listings that were eliminated duringthe attempt to create these from the modified maps included AST, AIRS,HMIRS, CERCLIS-NFRAP, RCRIS-SQG, MINES, FINDS,AZ_SPILL, RCRIS-LQG, UST, WWFAC, TSCA, and DRY WELL.The following are brief descriptions of each of the database listingsidentified in the EDR review:WQARF: Water Quality Assurance Revolving Fund Sites. Source:Arizona Department of Environmental Quality. These are sites whichmay have an actual or potential impact on the waters of the state, causedby hazardous substances. The state of Arizona has established aprogram under A.R.S. 49-22 to remedy these sites . In the WQARFprogram, the state takes actions to identify the extent and impact of thecontamination and to identify the parties responsible for remediation ofthe site. The WQARF program provides matching funds to politicalsubdivisions and other state agencies for clean-up activities. A reviewof the AZ WQARF list, as provided by EDR, and dated 12-28-99 hasrevealed that there is 1 AZ WQARF site within the Durango ADMParea. This site is referred to as the West Van Buren WQARF site.AIRS: Arizona Airs Database. Source: Arizona Department ofEnvironmental Quality. This database contains air pollution pointsources in Arizona that are monitored by the U. S. EnvironmentalProtection Agency and/or state and local air regulatory agencies. Areview of the AZ AIRS list, as provided by EDR, and dated 12-28-99has revealed that there are 4 AZ AIRS sites within the Durango ADMParea.AZ AQUIFER: Arizona Aquifers Database. Source: ArizonaDepartment of Environmental Quality. This database contains wastewater treatment facilities in Arizona that have Aquifer ProtectionPermits. A review of the AZ AQUIFER list, as provided by EDR, anddated 12-28-99 has revealed that there are 4 AZ AQUIFER sites withinthe Durango ADMP area.CORRACTS: Corrective Action Report Database. Source: U.S.Environmental Protection Agency. This database identifies hazardouswaste handlers with RCRA corrective action activity. A review of theCORRACTS list, as provided by EDR, and dated 12-28-99 has revealedthat there are 3 CORRACTS sites within the Durango ADMP area.PADS: PCB Activity Database System.
