remember to take the time to review this permit thoroughly, as some of the conditions contained
therein may have been added, changed, or deleted since the last issuance. Pay particular attention to the
monitoring requirements in this permit. Please be aware that failure to establish an adequate system for
collecting, maintaining, and submitting the required operational information will result in future
compliance problems.
If any parts, requirements, and/or limitations contained in this permit are unacceptable, you have

permit. This request shall be in the from of a written petition, conforming to Chapter 150B of the North

residual source -generating facility prior to acceptance of those residuals for distribution
through the approved Class A EQ residuals product distribution program.
4. All residuals and Class A EQ residuals product shall be adequately stored to prevent leachate
runoff. The Class A EQ residuals product may be stored in an elevated silo, placed on a

Division until such time as it is distributed to the user. If an alternative storage site is to be
used, approval shall first be obtained from the Division.
Adequate provisions shall be taken to prevent wind erosion and surface runoff from .
conveying pollutants from the Class A EQ residuals product.
