Petroleum Products Storage

__________ Ranking total from previous page |
divided by | ___________ number of areas ranked (14 if ranked all) |
equals | __________ | * |
*Carry your answer out
to one decimal place.
Example:
17 ÷ 9 = 1.89
Use 1.9
| 3.6 - 4.0 = low risk | 1.6 - 2.5 = moderate to high risk |
| 2.6 - 3.5 = low to moderate risk | 1.0 - 1.5 = high risk |
This ranking gives you an idea of how your petroleum product storage as a whole, might be affecting your drinking water. This ranking should serve only as a very general guide, not a precise diagnosis. Because it represents an averaging of many individual rankings, it can overlook any individual rankings (such as 1's or 2's) that should be of concern. (Step 2 will focus on individually ranked activities of concern.)
Enter your boxed petroleum product storage risk ranking in the appropriate place in the table on the front of fact sheet #14. Later you will compare this risk ranking with other farmstead management rankings. Worksheet #13 will help you determine your farmstead's site conditions (soil type, soil depth, and bedrock characteristics), and worksheet #14 will show you how these site conditions affect your risk rankings.
Step 2: Evaluate your rankings for individual activities based on the following.
4's Best: low-risk practices
3's Provide reasonable groundwater protection: low- to moderate-risk practices
2's Possibly inadequate protection: moderate- to high-risk practices
1's Inadequate protection with relatively high groundwater contamination risk: high-risk practices
| Regardless of your overall risk ranking, any individual rankings of "1" require immediate attention. Take care of some of the concerns right away; others could be major or costly project projects, requiring planning and prioritizing before you take action. |
Find any activities that you identified as 1's and list them under High-Risk Activities in fact sheet #13.
Step 3:
Read Fact Sheet #4, Improving Petroleum Products Storage, and
give some thought to how you might modify your farmstead practices to
better protect your drinking water. Refer to the Reference Organizations
for further information and assistance.
