G. A person who commences a regulated agricultural activity that is subject to an agricultural general permit adopted pursuant to this section shall immediately comply with the general permit.

H. The committee shall adopt and, as necessary and appropriate, amend by rule an agricultural general permit specifying best management practices, including recordkeeping and reporting requirements, for regulated agricultural activities to reduce fugitive PM-10 emissions. The committee shall adopt by rule a list of best management practices, at least one of which shall be used in areas designated as moderate nonattainment for PM-10 and at least two of which shall be used in areas designated as serious nonattainment for PM-10, to demonstrate compliance with applicable provisions of the general permit. Best management practices may vary within the regulated area, according to regional or geographical conditions or cropping patterns.

I. Fugitive PM-10 emissions from regulated agricultural activities that are subject to an agricultural general permit pursuant to this section are not subject to a permit issued pursuant to section 49-426 except as follows:

1. If the fugitive PM-10 emissions are from regulated agricultural activities at a stationary source that is otherwise required to obtain a permit pursuant to section 49-426, the permit issued pursuant to section 49-426 shall be subject to conditions as necessary to ensure compliance with federal, state and county regulations approved as a part of the state implementation plan, including regulations adopted under section 110(a)(2)(c) of the clean air act.

2. A person for whom an agricultural general permit has been revoked under subsection L of this section must obtain a permit pursuant to section 49-426 that includes enforceable conditions that impose best management practices on fugitive PM-10 emissions from regulated agricultural activities.

J. If a person who is engaged in a regulated activity is not in compliance with the general permit and that person has not previously been subject to a compliance order issued pursuant to this section, the director may serve on the person by certified mail an order requiring compliance with the general permit and notifying the person of the opportunity for a hearing pursuant to title 41, chapter 6, article 10. The order shall state with reasonable particularity the nature of the noncompliance and shall specify that the person has a period that the director determines is reasonable, but is not less than sixty days, to submit a plan to the supervisors of the natural resource conservation district in which the person engages in the regulated activity that specifies the best management practices from among those adopted in rule pursuant to subsection H of this section that the person will use to comply with the general permit.

K. If a person who is engaged in a regulated activity is not in compliance with the general permit, and that person has previously submitted a plan pursuant to subsection J of this section, the director may serve on the person by certified mail an order requiring compliance with the general permit and notifying the person of the opportunity for a hearing pursuant to Title 41, Chapter 6, article 10. The order shall state with reasonable particularity the nature of the noncompliance and shall specify that the person has a period that the director determines is reasonable, but is not less than sixty days, to submit a plan to the department that specifies the best management practices from among those adopted in rule pursuant to subsection H of this section that the person will use to comply with the general permit.

L. If a person fails to comply with the plan submitted pursuant to subsection K of this section, the director may revoke the agricultural general permit for that person and require that the person obtain an individual permit pursuant to section 49-426. A revocation becomes effective after the director has provided the person with notice and an opportunity for a hearing pursuant to Title 41, Chapter 6, article 10.

M. The committee shall develop and commence an education program. The education program shall be conducted by the director or the director’s designee or designees.

N. The regulation of fugitive PM-10 emissions produced by regulated agricultural activities is a matter of statewide concern. Accordingly, except for rules incorporated into the applicable implementation plan, this section preempts further regulation of fugitive PM-10 emissions from regulated agricultural activities by a county, city, town or other political subdivision of this state.
