Dr. Corely,
The Division does not believe there is a violation of the Act, or permit conditions required by the Act, or that any imminent
danger or harm exists that initiates Rule 5.02.5. The area of the channel embankment that has been documented as 'bare
of rip rap' is considered a maintenance item and does not rise to a violation. Additionally, the Division has only conducted
rough measurements of the Magpie Diversion and not a survey of the ditch. Currently, the Division and the Office of Surface
Mining Reclamation and Enforcement will be conducting a survey of the Magpie Diversion on a tentative date of April 4,
2018. Finally, based on the inspections conducted by the Division since August 2001 and the approval of the Magepie
Creek Diversion as a permanent drainage, there are no reasons to believe imminent danger or harm exists. However, the
Division will be conducting its monthly inspection of the Southfield Mine on March 30, 2018 at 9:00 AM which is within 10
days of receipt of your inspection request.
Additionally, there have been recent organizational changes within the Division. Jim Stark has now been promoted to the
Division's Program Supervisor and Jason Musick has taken his old position as an EPS Senior and my direct supervisor.
have remained the lead inspector for the Southfield Mine.
Sincerely,

Jim and Zach,
The Corley Company would like to request an inspection of the Magpie Diversion pursuant to 5.02.5. The permit
violation issues are listed below.
1. The Diversion was constructed as a temporary diversion and surveyed in 1982. This survey was reproduced for
Southfield in 1989 and was used for the certified as -built Southfield Map 25. It is impossible for this certification of the
temporary diversion to be used for the certification of the permanent diversion construction done in 2001. There has
never been a certification of the permanent Diversion by a qualified and registered professional engineer as required by
4.05.4(2) and 4.05.4(4).
2. There is an area on the north Diversion bank that is bare of rip -rap. This bare area has been noted in the monthly
Southfield inspection reports as requiring repair for about fifteen consecutive monthly reports.
3. The north bank of the Diversion has less than the required freeboard as specified in the Southfield Map 25A. A
survey certified by John H. Keilers, professional land surveyor, 23890, dated July 11, 2016, has been furnished to you.
The inadequate freeboard height was confirmed by subsequent measurements performed by the Division.
4. The Diversion discharge culvert beneath the Monarch Fan Road has a damaged inlet, which damage reduces the
inlet cross sectional area. The Federal Highway culvert tables do not provide flow data for damaged inlets, but it
seems probable that the reduced inlet area will thereby decrease the flow and increase the inlet head water height.
5. The Diversion of Magpie Creek does not return the water to the original Magpie Creek at the culvert inlet. Instead
the Diversion flow joins an unnamed creek at the culvert outlet, and the Diversion flow continues about three-quarters
of a mile downstream, outside the Southfield permit area, and across the neighboring Warnock property where it rejoins
the original Magpie Creek.
This inspection request if being made now because of the approaching rainy season. Breaching of the north bank of
the Diversion at the location of the inadequate freeboard may cause severe damage to the portal area reclamation.
