The Illinois Environmental Protection Agency (IEPA) has made a tentative determination to issue a NPDES permit to discharge into the

waters of the state and has prepared a draft permit and associated fact sheet for the above named Permittee. The Public Notice period

will begin and end on the dates indicated in the heading of this Public Notice/Fact Sheet. The last day comments will be received will be

on the Public Notice period ending date unless a commentor demonstrating the need for additional time requests an extension to this

comment period and the request is granted by the IEPA. Interested persons are invited to submit written comments on the draft permit to

the IEPA at the above address. Commentors shall provide his or her name and address and the nature of the issues proposed to be

raised and the evidence proposed to be presented with regards to those issues. Commentors may include a request for public hearing.

If written comments or requests indicate a significant degree of public interest in the draft permit, the permitting authority may, at its

discretion, hold a public hearing. Public notice will be given 45 days before any public hearing. Response to comments will be provided

when the final permit is issued. For further information, please call Mark E. Liska at 217/782-0610.

The applicant is engaged in in the operation of a tank farm connected to the Cochin Pipeline and Explorer Pipeline (SIC 4613). Waste

water is generated from the discharge of hydrostatic test water during new tank construction. Construction of the tank farm will result in

a discharge of 8.4 MGD of hydrostatic test water from outfall 001.

To assist you further in identifying the location of the discharge please see the attached map.

The unlisted stream segment receiving the discharge from outfall(s) 001 is not on the 2012 303(d) list of impaired waters and is not a

biologically significant stream on the 2008 Illinois Department of Natural Resources Publication Integrating Multiple Taxa in a Biological

Stream Rating System.

facilities in Fort Saskatchewan, Alberta, Canada. Reversal of the pipeline requires Kinder Morgan to construct the tank farm to allow

delivery of light condensate from an existing pipeline. Five storage (breakout) tanks and a pump station would be constructed northeast

of the intersection of W 7000S Road and S 8000W road in Section 6, Township 29 North, Range 11 East. Each tank would be

hydrostatically tested using onsite well water and discharged at a maximum rate of 3,000 gallons per minute into an energy dissipation

device prior to entering an onsite storm water retention basin. Discharges would occur from one large discharge event (8,400,000

gallons) over multiple days and up to five smaller discharges (10,000 gallons). Overflow from the retention basin (Outfall 001) would be

sent through a grass waterway with additional energy dissipation devices before being received by Gar Creek.

Identification and Characterization of the Affected Water Body.

Parameters that would increase in loading are associated with the groundwater used for testing and the residual materials in the new

tanks and piping. Dissolved iron would likely be present in the well water but would become oxidized upon discharge. Total suspended

solids and oil and grease may be present in the new tanks, pipes, valves and fittings but these additions are expected to be minimal. No

adverse impact to Gar Creek is anticipated from the hydrostatic tests.

Fate and Effect of Parameters Proposed for Increased Loading.

Iron and total suspended solids would be regulated by the state effluent standards and would become part of the bed sediment of the

receiving waters. Oil and grease would also be regulated with the state effluent standard and therefore no visible remnant may be

Assessments of Alternatives for Less Increase in Loading or Minimal Environmental Degradation.

The pipeline owner has chosen responsible methods of hydrostatic testing. Well water from the local aquifer would be used for testing

and discharged to Gar Creek. Erosion control measures would be applied at the points of discharge into and from the retention basin.

This consists of straw bales or geotextile structures placed in a manner to disperse energy and filter particles. The hydrostatic test

methods chosen are the accepted norm for these projects. Hydrostatic testing is a very short-term activity. Arranging for effluents to be

land applied, sent to a POTW or other alternatives are not practical for this type of discharge. Discharging the effluents to local surface

waters in a responsible manner has been developed as the proper method of dealing with the water needed for the testing.

Agency Conclusion.

This preliminary assessment was conducted pursuant to the Illinois Pollution Control Board regulation for Antidegradation found at 35 Ill.

Adm. Code 302.105 (antidegradation standard) and was based on the information available to the Agency at the time the draft permit was

written. We tentatively find that the proposed activity will result in the attainment of water quality standards; that all existing uses of the

receiving stream would be maintained; that all technically and economically reasonable measures to avoid or minimize the extent of the

proposed increase in pollutant loading have been incorporated into the proposed activity; and that this activity will benefit the communities

at large by ensuring the safety of the tanks and pipeline. Comments received during the NPDES permit public notice period will be

evaluated before a final decision is made by the Agency.
