Four Categories Showing Long Term Annualized Costs of Compliance Statewide (2019 dollars)
Category of Facility | Count of Facilities in State (#) | Annual Capital And O&M Cost Per Year For Facility In A Category ($/facility/year) | Total Of Annual Capital And O&M Cost Per Year For State For All Facilities In A Category ($/state/year) |
State total for all categories | 28 | NA | 12,971,574 |
Based on these estimates, the long term annual cost to come into compliance with the federal rule for the entire state is $13 million per year (2019 dollars). The total in any 2-year window would be two times the long term annual cost or $26 million for a two year period (2019 dollars).
In conclusion, costs are difficult to estimate because the cost of technology will depend on case-by-case permit decision for each facility. The costs here are based on lower end estimates of likely scenarios.
