Section NR 408.10 - Source obligation(1) Any owner or operator who constructs or operates a stationary source or modification not in accordance with the application submitted under this chapter or with the terms of any approval to construct, or any owner or operator of a stationary source or modification subject to this chapter who commences construction after June 1, 1993 without applying for and receiving approval as described in this chapter, shall be subject to enforcement action and penalties as provided in ch. NR 494.(2) The approval to construct or modify a stationary source shall become invalid 18 months after the date a construction permit is issued by the department unless the permit specifies otherwise. The department may extend the 18 month period upon a satisfactory showing that an extension is justified unless otherwise specified in the construction permit.(3) The approval to construct does not relieve any owner or operator of the responsibility to comply fully with applicable provision of chs. NR 400 to 499 or any other requirements under local, state or federal law.(4) At the time that a particular source or modification becomes a major source or major modification solely by virtue of a relaxation in any enforceable limitation which was established after August 7, 1980, on the capacity of the source or modification otherwise to emit a pollutant, such as a restriction on hours of operation, then the requirements of ss. NR 408.04 to 408.09 and this section shall apply to the source or modification as though construction has not yet commenced on the source or modification.(5) For a project involving existing emissions units at a major stationary source, which does not have a PAL, in circumstances where the calculated difference between projected actual emissions using the method specified in s. NR 408.02(28s) (b) 1. and 2., and baseline actual emissions does not exceed the level that is considered to be significant for the air contaminant, the owner or operator shall do the following as applicable: (a) Before beginning actual construction of the project, document and maintain a record of all of the following: 1. A description of the project.2. Identification of the emissions unit or units whose emissions of a regulated NSR air contaminant could be affected by the project.3. The calculation of the net emissions increase under s. NR 408.02(23) (a) that was used to determine that the project is not a major modification for any regulated NSR air contaminant, including the baseline actual emissions, the projected actual emissions, the amount of emissions excluded under s. NR 408.02(28s) (b) 2. and an explanation why the amount was excluded, and any netting calculations, if applicable.(b) If the emissions unit is an existing electric utility steam generating unit, before beginning actual construction, provide a copy of the information in par. (a) to the department. Nothing in this paragraph shall be construed to require the owner or operator of the unit to obtain any determination from the department before beginning actual construction.(c) If the owner or operator excludes emissions from the calculation of projected actual emissions under s. NR 408.02(28s) (b) 2. and the difference between projected actual emissions and baseline actual emissions exceeds the level that is considered to be significant for the air contaminant prior to the exclusion of emissions from the calculation of projected actual emissions under s. NR 408.02(28s) (b) 2., before beginning actual construction, provide a copy of the information in par. (a) to the department. Nothing in this paragraph shall be construed to require the owner or operator of the unit to obtain any determination from the department before beginning actual construction.(d) Monitor the emissions of any regulated NSR air contaminant that could increase as a result of the project and that is emitted by any emissions unit identified in par. (a) 2. and calculate and maintain a record of the annual emissions, in tons per year on a calendar year basis, for a period of 5 years following resumption of regular operations after the change, or for a period of 10 years following resumption of regular operations after the change if the project increases the design capacity or potential to emit of that regulated NSR air contaminant at the emissions unit.(e) If the unit is an existing electric utility steam generating unit, submit a report to the department within 60 days after the end of each year during which records must be generated under par. (d) setting out the unit's annual emissions during the calendar year that preceded submission of the report.(f) If the unit is an existing unit other than an electric utility steam generating unit, submit a report to the department if the annual emissions, in tons per year, from the project identified in par. (a), exceed the baseline actual emissions, as documented and maintained pursuant to par. (d), by a significant amount, as defined in s. NR 408.02(32) for that regulated NSR air contaminant, and if the emissions differ from the preconstruction projection that was provided to the department pursuant to par. (c). The report shall be submitted to the department within 60 days after the end of the year. The report shall contain all of the following: 1. The name, address and telephone number of the major stationary source.2. The annual emissions as calculated pursuant to par. (a) 3.3. Any other information that the owner or operator wishes to include in the report, e.g., an explanation as to why the emissions differ from the preconstruction projection.(6) The owner or operator of the source shall make the information required to be documented and maintained pursuant to sub. (5) available for inspection, upon request, by the department or the general public.Wis. Admin. Code Department of Natural Resources NR 408.10
