Re: Corning Incorporated — Midland Facility
NPDES Permit Number 86169
Authorization to Construct Request
Dear Mr. Goodrich:
Enclosed are three (3) sets of design documents supporting our request for Authorization to Construct in association
with the our December 20000 request for expansion at Corning's Midland, NC facility.
As was summarized in our above referenced permit modification request (currently under review by Mr. Mike Myers of
your office), Corning is proposing an expansion of the optical fiber manufacturing facility in Midland, Cabarrus County.
Process effluent from the fiber optics manufacturing process will continue to consist primarily of blowdown from the air
pollution control equipment. It is proposed that the facility will treat the new process effluent as it does the existing
process effluent, through a fairly simple Pollution Abatement System consisting of lamella clarifiers for solids removal
and neutralization for pH adjustment. The expansion of the Pollution Abatement System will consist of the following:
• A 60,000 gallon Saleable Acid Tank;
• A 10,000 gallon Reject Acid Tank;
• Modifications to several of the existing process pumps; and
• And modifications to an existing 3,000 gallon effluent lift station.
This request for Authorization to Construct includes detailed plans and specifications signed and sealed by a
Professional Engineer registered in the State of North Carolina and responses to all issues addressed in the NPDES
Unit's Authorization to Construct Requirements guidance document. Any drawings or specifications that may change
during the ongoing design effort and/or construction will be sent to DWQ with the engineer's certification.
In an effort to begin construction as soon as possible, Corning respectfully requests that, if possible, the Authorization to
Construct be issued concurrently with issuance of the pending permit modification. If any further information is
required in order to expedite the approval process, please feel free to contact me at [phone].
Sincerely,
Corning Incorporated
