If the preventive action level is exceeded, the utility shall perform the remaining four tests, except as provided in § 20:10:39:21. The utility shall also perform an analysis to determine whether the portion of the stray current or voltage attributable to an off-farm source exceeds 50 percent of the preventive action level.
If the preventive action level is exceeded and the portion of the stray current or voltage attributable to an off-farm source does not exceed 50 percent of the preventive action level, the utility has no further testing or remediation obligations.
If the preventive action level is exceeded, and the portion of the stray current or voltage attributable to an off-farm source exceeds 50 percent of the preventive action level, the utility shall conduct remediation pursuant to SDCL 49-47-3. Under this condition, the 48 hour recording of the 48 hour test may be reduced to no fewer than 24 hours.
