What is the minimum quantity available for delivery?

Texas Brine has established a minimum quantity of 4,000 gallons per load as a minimum,
primarily for safety purposes. Texas Brine's delivery trailers vary in quantity from 4,100
gallons to 5,000 gallons. We prefer to operate the trailers full or empty (or minimal residual
volumes) to reduce slosh while turning and/or braking.

For what time period may a truck be detained at my facility prior to incurring an additional charge?

A demurrage charge will be applied should a customer-caused delay beyond two (2) hours
occur within their facility. As of March 2008, the rate is $65.00 per hour. Any time in
excess of the aforementioned two (2) hours will be prorated to the next quarter (15 minute
interval) hour.
