Our catalog price for a spill plan is $475.00 to $650, for most tank batteries, depending on how many plans you're doing at one time. If you have a centralized unit or large facility with more than 10 tanks or vessels then the price is subject to each location. We price spill plans based on size and location. Our pricing is more than some companies, and less than others. However, we help you with audits you receive and update all your plans as needed for 5 years at no additional charge. If you change tanks two years down the road then let us update your plan at no charge.
