For this reason, we ask <br />for these modifications to be granted as a Class I under TAC 305.69(e)(2)(A), <br /> <br />"Class I modifications apply to minor changes that keep the permit current with routine changes to <br />the facility or its operation. These changes do not substantially alter the permit conditions or reduce <br />the capacity of the facility to protect human health or the environment. II <br /> <br />The hazardous waste stream is classified as 0001 due to the tetrahydrofuran (9%) in the stream. <br /> <br />Included in this application are the following attachments: <br /> <br />Attachment I - Section I of Part B Permit Application with Signature page. <br />Attachment II - Check for $150 <br />Attachment 11I- Mailing Addresses of Adjacent Land Owners <br />Attachment IV - Waste CharacterizatiQn Forms and Applicable MSOSs <br />Attachment V - Revised permit <br /> <br />If there are any questions, or if I can be of assistance, please contact me at (281) 470-3027. <br /> <br />Sincerely, <br /> <br />~ 1( 6~ <br /> <br />Russell K.
