ATTACHMENTS — provide the following information in separate attachments. The attachments should be clearly identified and presented in the order below to expedite review of the permit application package. 1. INJECTION ZONE — Specify the horizontal and vertical portion of the subsurface within which the proposed injection activity will take place and beyond which no violations of groundwater quality standards shall result from the injection as determined by an approved monitoring plan. The determination shall be based on the hydraulic properties of the specified zone. Provide any supporting documentation in a separate attachment. 2.
