  5. 2010 Year End Gas Statistics for South Dakota • Gas transmission mileage 222 • Gas distribution mileage 4,483 • Number of gas services 202,990

  6. SD Gas Distribution Federal Reportable Incident Summary1998 – 2011

  7. Enforcement Statistics 2011

  8. Declaratory Ruling -Pipeline Classification • It is possible to have a transmission line under 20 % SMYS. • A distribution center begins at the location of title transfer. • A pipeline feeding a large volume customer is no longer distribution if it is < 20 % SMYS but must be downstream of a distribution center to be distribution. • This could affect operators that may in the future have a large volume customer tapped into an interstate transmission line at a point other than a distribution center with a line operating at < 20 % SMYS.  In such a case, this may now possibly be transmission rather than distribution.

  9. Major Construction Activity • None • System expansion activity in distribution systems • No new transmission lines

  10. Special Permits Requested / Granted • None in 2011
