7/17/2014 Perry requested that I provide the information we previously discussed in written format. I sent him the below email: From: Knoll, David [DNR] Sent: Wednesday, July 02, 2014 2:28 PM To: Dargitz, Perry D (Mason City) USA (Perry.Dargitz@LehighHanson.com) Cc: Carper, Glenn [DNR] Subject: Building Expansion for Monitoring Equipment Perry, Per your request, I am responding to your inquiry regarding whether or not an air quality construction permit revision is needed when performing a building expansion to house air monitoring equipment on an existing emission unit. The language below describes when a permit needs to be revised. Based on the information you provided, the emission unit, control equipment, and emission point will remain unchanged by the expansion project to house the monitoring equipment. Therefore, no permit revisions would be required. If you would like further information regarding permitting, I would recommend contacting the Construction Permits staff in Windsor Heights at 515-725-9549. The permit is for the construction and operation of specific emission unit(s), control equipment, and emission point as described in this permit and in the application for this permit. Any owner or operator of the specified emission unit(s), control equipment, or emission point, including any person who becomes an owner or operator subsequent to the date on which this permit is issued, is responsible for compliance with the provisions of this permit. No person shall construct, install, reconstruct or alter this emissions unit, control equipment or emission point without the required revisions to this permit.

6/2/2014 Perry asked if he needed to amend his AQ construction permit if he plans to add monitoring equipment for PM and mercury to the main stack. I explained that as long as he is not changing the physical stack characteristics and not altering the equipment or control equipment connected to the emission point, no permit amendment is needed. Perry reiterated that the only change would be adding the monitoring equipment. I stated that no permit amendments would be needed in that scenario. DAVID KNOLL
