RE: New Source Review Permit Amendment - Permit Number: l 12006-005F Project Number: 2019-10-017; Installation Number: PORT-0565

Dear Mr. Thiltgen:

On October 8, 2019, Air Pollution Control Program received your request to amend Permit# 112006-005 by changing Special Condition 2 (for Hwy 63N Quarry only) from a National Ambient Air Quality Standards (NAAQS) Limitation for particulate matter less the ten microns in diameter (PM10) to a daily throughput limitation.

The ambient impact from Permit #112006-005 is being converted to daily production limits. This change reflects the Air Pollution Control Program's updated construction industry policy "Ceasing the Use of Nomographs" dated May 1, 2016.

According to Department ofNatural Resources Air Pollution Control Program's database, the only other portable plant that has been permitted to operate at the Hwy 63N Quarry (Site ID 019-0050) is PORT-0505, and it is being amended (Project 2019-10-013) to change from a NAAQS limit to a daily production limit as well. Both PORT-0505 and PORT-0565 are both portable rock crushers and typically do not operate at this quarry at the same time. The following scenarios includes that option.

PORT-0565 is permitted to operate with other plants located at the Hwy 63N Quarry (Site ID O19-0050) as long as the following scenarios are maintained. These scenarios are also summarized in the table below.

• When operating by itself, referred to as solitary operation, that does not have a NAAQS daily limit, PORT-0565 has a daily production limitation of 13,127 tons per day.

• When operating concurrently with a plant owned by Capital Quarries/Capital Materials or a separate owner plant, PORT-0565 is allowed to produce up to 7,094 tons per day.
