SIP Package: Redesignation Demonstration and Maintenance Plan for the York 

County portion of the Charlotte-Gastonia-Rock HiU NC-SC Nonattainment Area 

Dear Ms. Keyes Fleming: 

The South Carolina Department of Health and Environmental Control (Department) is pleased to 

submit the Redesignation Demonstration and Maintenance Plan for the York County portion of 

the Charlotte-Gastonia-Rock Hill NC-SC 8-hour Ozone (Metrolina) Nonattainment Area. 

Enclosed is the complete package containing the redesignation demonstration for the York 

County portion of the Metrolina nonattainment area, along with certified air quality data, and a 

maintenance plan which fulfills the requirements of Section 175A of the Clean Air Act as 

amended. 

A public notice to revise the State Implementation Plan (SIP) was published in the State Register 

on March 25, 2011, and is included as Attachment E in this package. The State Register notice 

referenced a 30 day comment period that would conclude on April 25, 2011 , however, due to a 

delay in the associated documentation, the Department extended this comment period to coincide 

with the proposed public hearing date of May 2, 2011. A public hearing on this issue was offered 

on May 2, 2011; however, the Department did not receive a request for a public hearing and it 

was thereby cancelled, as allowed by 40 CFR 51.102. The department did receive comments 

regarding its pre-hearing submittal from the EPA. These comments, along with Department 

responses, are included as Attachment F.
