(g) The name of the facility representative who acknowledged receipt of the waste and the amount of waste received.
(6) The generator is required to obtain a signed copy of the record and retain it for 12 months from the date the waste is received by the transporter for review by city officials, the Grayson County Health Department, and annual reports required from the transporters to the Texas Natural Resource and Conservation Commission.
(7) Transporters of grease trap waste must be registered with the Texas Water Commission.
(8) Have a five-digit registration that is preceded by “TNRCC” and followed by a two-digit number assigned by the Grayson County Health Department for identification.
