B. The water removal system must have adequate capacity to remove water at a rate equal to 25 percent of the maximum predictable collection rate from a storm of 10-year frequency and 1-hour duration, and other natural causes. For rainfall amounts, operators must use the "Rainfall Frequency Atlas of the United States" published by the National Weather Service of the U.S. Department of Commerce. [49 CFR 193.2173(b)]

C. Sump pumps for water removal must:

1. be operated as necessary to keep the impounding space as dry as practical; and [49 CFR 193.2173(c)(1)]
