distinctions between inland and offshore oil spill scenarios, there are also important distinctions in spill response strategies in the inland and offshore environments (see Appendix A)

For example, the USCG Inland ERSP Calculator is not designed to consider situations where there is little to no current in a stagnant body of water, or situations where flow to a collection point has been impeded by changing characteristics of the nearshore environment that affect flow direction and flow regime. These location-specific details are important for response planning in the inland environment.

A calculator designed to accomplish tasks of both regulatory planning and predictive modeling is difficult to use and inherently must sacrifice certain aspects of each. As currently designed, the USCG Inland ERSP Calculator falls in the middle of the planning and predicting continuum, having incorporated a larger number of parameters reflective of specific response scenarios than the BSEE ERSP Calculator, but not in sufficient detail to accurately predict the specific operating conditions that are required for development of oil spill response plans.

, the intended users of the USCG Inland ERSP Calculator are "not oil spill experts, but plan holders responsible for developing oil spill response plans for their facility/vessel located in the inland environment." Furthermore, oil spill removal organizations (OSROs) may "also use the calculator to determine the approximate estimate of spill recovery equipment that may be needed for spills in the inland environments." The committee believes that the value of the calculator's output is highly dependent upon the skill level of the user.

From page 13... ...
Oil spill planners have a primary concern in ensuring that the contracted response resources listed in their plan meet the applicable regulatory requirement. Because the USCG Inland ERSP Calculator's output does not consider its impact on the existing regulatory planning standard, it may have limited importance and use to the planner.

From page 14... ...
The committee considered the criteria of tracking the calculator methodology to estimate appropriate oil skimmer response planning capacities and understanding the relative significance of the inputs on the estimated output when evaluating the calculator's transparency. Regarding the clarity of the outputs, the committee reviewed how the calculator presents the result as well as the clarity and appropriateness of the detail provided in the output for planning decisions.

3. Provide recommendations for improving ERSP methodologies, if any, to inform oil spill planning and preparedness for the inland and nearshore environments; and ● Methods for developing calculator concept ○ It is important that USCG and users are cognizant of on-water mechanical recovery's typically lesser role in cleanup of inland spills versus offshore spills and consider all feasible options for response measures; the utilization of this calculator to improve specific response plans could con sider site-specific geographic response plans (GRPs)

○ Link an actual oil spill model (e.g., SIMAP used by the project team to generate lookup tables for the Oil Behavior Module) to more accurately predict oil fate and behavior as well as equip ment efficiency at a certain location and within a specific scenario.
