F. Any unpermitted facility or activity that exists or is under construction on the effective date of these regulations and falls under the jurisdiction of Subsection B of this Section shall submit a completed application to the Office of Environmental Services within 180 days of the effective date. Upon receipt of the application by the department within the prescribed 180 days, the facility shall be deemed in compliance with Subsection B of this Section except where the administrative authority has initiated action against the facility following an investigation or complaint. All facilities or activities that meet the requirements outlined in Paragraph J.4 or K.4 of this Section shall be exempt from the requirements of this Subsection. G. When a facility or activity is owned by one person but is operated by another person, it is the operator's duty to obtain a permit. H. On the effective date of these regulations the status of state permits shall be as follows. 1. All LWDPS permits shall be issued for a period not to exceed five years. 2. All existing state permits issued prior to January 1, 1980 shall expire within one year of the effective date of these regulations. 3. All existing state permits issued subsequent to January 1, 1980 shall expire six years after their effective date. I. Upon delegation of the NPDES program to the state, the status of NPDES permits shall be as follows. 1.

For facilities with both NPDES and existing state permits, the NPDES and existing state permit shall be consolidated into one permit. In case of conflicting permit requirements the more stringent requirement will control. This consolidated permit will be adopted as a LWDPS permit effective upon receipt by the permittee of written notification by the state and shall remain effective for a period in accordance with LAC 33:IX.301.H above (the NPDES permit expiration date shall be void).
