(c) Specific geographic area graywater reuse and disposal system WPCF general permit.

(A) When necessary to protect public health or the environment, the department may issue a graywater reuse and disposal system WPCF general permit that covers a specific geographic area.

(B) A person required to be covered under a graywater reuse and disposal system WPCF general permit for a specific geographic area must apply for permit coverage as directed by the geographic area graywater reuse and disposal system WPCF general permit.
