### ExhibitA PolkCountyBoard ofHealthRules and Regulations- ChapterV Air Pollution 9/1/2015 

### Summary ofProposedActions (Items 1

### and 2): Routineupdates and addition ofdefinitions for consistency with 567 Iowa Administrati"e Code (lAC) references and definitions. Theproposed amendments are a routine updateto bringthe Board ofHealthRules and Regulations, Chapter
V-AirPollutionup-to-date\vith 567 IO\va Administrative Code (IAC). 

### (Items 3, 4 ancl 5): Rescind NSPS and NESHAP standards. The rescissions proposed for airtoxics and new sourceperformance standards affect industries that do not currently operate in Iowa, and are unlikelyto operate in IO\va in the future. In a recent rulemaking, the IDNR rescindedthese standards from the IO\va Administrative Code. 

### (Item 6): NSPS and NESHAP standards adoption by

### reference. ThePublicWorksDepartmentproposesthe adoption offederal airtoxics standards (NESHAP) and ne\v

source performance standards (NSPS),whichwillprovideregulatory benefits. Publichealth\Vill benefit
from reductions in air toxics controlledundertheNESHAP. Owners and operators ofaffected facilities must comply with federal air toxics standards regardless ofwhetherthe county incorporatesthese federal standards into the Board ofHealthRules and Regulation, ChapterV-AirPollution. Therefore, the incorporation by reference ofthe federal standards will not impose any additional costs to the affected facilities. TheDepartmentproposesto adopt amendments to existing air toxics standards and NSPS that generallyprovideflexibility and clarity, and do notimpose additional costs to most affected facilities. 

### (Items 7, 8, 9, 10, 11 and 12): PermitExemptions The Public \Vorks Departmentproposes rule changesto some ofthe construction and operating permit exemptions in support ofthe currentN0tion:1l Ambient Air Quality Standards (NAAQS) for PCirticuiC1te
Matter (PM2.5), Lead, Sulfur Dioxide (S02), and Oxides ofNitrogen (NOx). To provideregulatory flexibility, the permit exemptions are for low-emitting sources.1. Article
