Offsite Areas = 100m spacing out to 2km; 500m spacing for 2-5km; 5000m spacing for 5-50km (SIP).

Public Roadway Ambient Air Exclusion Areas: within 5m to 15m from edge of nearest traffic lane:

5m for low ADT (<500 ADT); 10m for medium ADT (500-3000 ADT); 15m for high ADT (>3000 ADT).

Some things to consider in deciding on when to re-evaluate and/or when to submit and/or require MPCA approval: 

-- How likely the facility is to make modifications that would increase the PTE of the pollutant(s) that was/were modeled;

-- Does the facility make routine changes to units/sources that have low emissions but poor dispersion (e.g., heat recovery, fugitives);

-- Was the modeled required by a rule or was the decision to complete it based on policy or some case-by-case decision;

-- How well do the operating assumptions used in the modeling resembling how the facility actually operates;

Any permit team recommendation on this issue shall be documented in the permit technical support document and shall

include a discussion of the above factors.

* The default level of modeling is as stated; however, individual permit teams may

-- Does the permit already prohibit the facility from increasing 

-- Does the facility have a wide range of letter grades for one pollutant.
