The applicable calendar year is the year after the three calendar years used to determine whether a facility is a very small business. The most recent applicable calendar year is the current year. For example, on June 3, 2024, 2024 is the most recent applicable calendar year and is the applicable calendar year when the three calendar years used to determine whether a facility is a very small business are 2021-2023. The exception is when three calendar years of records are not available, such as when a facility begins business after the compliance date for very small businesses. In such situations, the applicable calendar year refers to the year during which the calculation is made but is not preceded by 3 calendar years used to determine whether a facility is a very small business.
