D. Do not uncover, sample, or abandon the existing water main before Written Authorization to Proceed and before required shoring, monitoring, RailPros observation, and UPRR flagging are in place.

E. If UPRR does not approve abandonment in place as contemplated by the Contract Documents, or imposes additional testing or other requirements after the Bid Date that materially affect the Work, do not proceed with the affected work until the Engineer of Record provides written direction. Resulting changes will be administered in accordance with the Contract's change provisions.

F. Completely fill the water main authorized to remain in place, verify that no voids remain, and document the limits, method, quantity of fill, placement, and verification.

(q) Natural organic or nutrient producing ma terial shall not be used during the construction, reconstruction, or treatment of a well unless it is thoroughly’ flushed from the well and the ground water aquifer or aquifers before the well is coin pleted. Natural organic or nutrient producing ma terial shall not be added to a grout mix used to grout the well’s annular space.

(r) Pump mounting.

(1) All pumps installed directly’ over the well casing shall be so installed that an airtight and wa— tertight seal is made between the top of the well casing and the gear or pump head. pump foun dation or pump stand.

(2) W’hen the pump is not mounted directly’ over the well casing and the pump column pipe or pump suction pipe emerges from the top of the well casing. a sanitary well seal shall be installed between the pump column pipe or pump suction pipe and the well casing. An ththglit and water tight seal shall be provided for the cable conduit when submersible pumps are used.

(5) Cunstruction of sand point or well point wa ter wells. Sand point or well point water wells shall be constructed by drilling or boring a pilot hole to a minimum depth of three feet below ground sur face. The pilot hole shall be a minimum of three inches greater in diameter than the drive pipe or blank casing if the casing method is used. Sand point wells shall only be completed by using the casing method or the drive pipe method as de scribed in paragraphs (1) and (2) below or other methods as described in paragraph (3) below.

Sand point wells constructed prior to the effective date of this regulation shall not be required to meet these requirements. All sand point wells that are replaced. constructed, reconstructed or plugged after the effective date of this regulatim shall meet these regulations.

The casing shall be sealed between the casing and the pilot hole with approved grouting material from the bottom of the casing to ground surface. The drive pipe shall be considered the pump drop pipe. For under ground discharge completions, a ‘f’ joint shall be used. The drive pipe shall be capped with a solid cap at the “T” joint when the casing method is used. An approved sanitan’ well seal and a well vent shall be installed on the top of the well casing in accordance with K.A.R. 28-30-6 (0 and (k).

The annular space betxveen the drive pipe and the pilot hole shall be sealed with approved grouting material from the bottom of the pilot hole to ground surface. The top of the drive pipe shall be sealed airtight and watertight with a solid cap of the same material as the drive pipe. A well vent shall not be required for the drive pipe niethod.

(.3) Other methods. Other methods may’ be spedficall approved by the department on a case-by-case basis by using the appeal procedure in cluded in K.A.R. 28-30-9.

(4) Abandonment of sand point wells. Upon abandonment of a sand point well, the contractor or landowner shall either pull the drive pipe or leave it in place. If the drive pipe is left in place, the sand point well shall be plugged from the bot tom of the well to three feet below the ground surface with approved grouting material, The drive pipe well shall be cut off three feet below the ground surface and the remaining three foot deep hole shall be backfilled with surface soil.

If the drive pipe is completely pulled, the re maining hole shall be plugged with approved grouting material from the bottom of the remain ing hole to three feet below the ground surface.

The hole shall be backfilled with surface soil from 3 feet to ground surface. (Authorized by K.S.A.
