For the worst-case and alternative release scenarios of an underground storage tank, should I consider any impact on groundwater, drinking water or soil?
No. As part of the worst-case and alternative release scenarios, you need to define the offsite impacts to the environment (40 CFR 68.33) by listing the environmental receptors that are withing your impact zone. “Environmental receptor” is defined at 40 CFR 68.3 as “natural areas such as national or state parks, forests, or monuments; officially designated wildlife sanctuaries, preserves, refuges, or areas; and Federal wilderness areas” which could be exposed to an accidental release. You only need to list the environmental receptors, not speculate what specific damage could occur as a result of an accidental release. You should, however, consider impacts on groundwater, drinking water or soil in both the accident history for Program 1 eligibility criterion (40 CFR 68.10(b)(1)) and the five-year accident history required as part of the hazard assessment (40 CFR 68.42). For Program 1 eligibility, you must not have had an accidental release of a regulated substance in the past five years
