The following is a brief summary of the status of our current SCADA
capabilities on the Lost Creek pipeline: Madden West MDS Radio installed and functioning properly polling pressure and flow data correctly chromatograph appears to be functioning correctly setpoint capabilities have not yet been tested. We will need to have a field operator present on-site before performing this test. EFM data collection is being configured to correspond to ROCLINK, rather than our standard Enron MODBUS load, that is installed on the ROC polling H2S and H2O levels, but correct registers have not been verified yet Fred Novotny MDS radio installed and functioning properly polling pressure and flow data correctly chromatograph appears to be functioning correctly setpoint capabilities have not yet been tested. We will need to have a field operator present on-site before performing this test EFM data collection is being configured to correspond to ROCLINK, rather than our standard Enron MODBUS load, that is installed on the ROC polling H2S and H2O levels, but correct registers have not been verified yet Keith Baker MDS radio installed and was functioning properly lost communications with this site yesterday. Elkhorn has been notified and will have someone onsite today to inspect the ROC and comm package. In addition, I requested that the dispatched person take a laptop along to assist our IT group in confirming the register configuration on the RTU so that we can verify that we have correct H2S and H2O level readings at all of our meters. setpoint capabilities have not been tested. We will need to have a field operator present on-site before perfoming this test EFM data collection is being configured to correspond to ROCLINK, rather than our standard Enron MODBUS load, that is installed on the ROC Lysite Production Office MDS master radio and omnidirectional antenna installed and functioning properly UPS system installed POTS service to Paneltec installed and functioning CDPD service on hold awaiting decisions regarding 20/20 Lost Creek Plant Inlet POTS service to ROC installed and functioning polling pressure and flow data correctly chromatograph appears to be functioning properly setpoint capabilities have not been tested. This ROC controls inlet flow by modifying suction pressure on the C-101 compressor unit, so it appears that it must be tested with the unit operating and personnel on-site Lost Creek Plant Delta V Developing screens for Gas Control to view plant operations Have not installed Paneltec and RS-232 cable to enable polling at this time CIG/WIC Interconnect Meters CIG/WIC Access agreement has gone through Enron legal, but is being reviewed by Insurance at this time Once this has been approved, we have to have CIG/WIC agree to the new document to grant us access to the site Will have to construct new RTU building and install power, UPS, RTU, MDS radio and antenna at site to enable polling Lost Creek Plant Aux Control Bldg. Have not moved primary polling of all devices into the Aux. Control Bldg. Awaiting 20/20 decisions to determine routing and place order for 56K dedicated line to site Once clearance is granted, we will need to order and install a xyplex and hub in building. Assuming that we go with CDPD coverage at the north end of the system, this will serve as the collation point for all incoming/outgoing SCADA traffic via the 56K line Tower and antenna to be installed on site to enable polling of the CIG/WIC RTU Sand Draw We have good cellular coverage at this site, and wish to use cellular service to poll this RTU Because RTU is in a Class 1, Div. 2 area, trying to locate a compliant cellular package or go with cellular package capable of operating under WY winter and summer temperature conditions that can be installed external to the meter building Beaver Creek This site is on hold with regard to SCADA polling at this time If you have questions regarding this summary, please contact me at x36530.
