Code of Federal Regulations Title 36. Parks, Forests, and Public Property § 36.9.122 What additional reports must I submit if my operation includes hydraulic fracturing?

(a) The true vertical depth of the well;  total water volume used;  a description of the base fluid and each additive in the hydraulic fracturing fluid, including the trade name, supplier, purpose, ingredients;  Chemical Abstract Service Number (CAS);  maximum ingredient concentration in additive (percent by mass);  and maximum ingredient concentration in hydraulic fracturing fluid (percent by mass). This information may be submitted to the Superintendent through FracFocus or another existing database available to the public;

(b) The actual source(s) and location(s) of the water used in the hydraulic fracturing fluid;

(c) The maximum surface pressure and rate at the end of each stage of the hydraulic fracturing operation and the actual flush volume;

(d) The actual, estimated, or calculated fracture length, height and direction;

(e) The actual measured depth of perforations or the open-hole interval;

(f) The actual volume of stimulation fluids recovered during flow back, including a description of how the volumes were measured or calculated;

(g) The following information concerning the handling of fluids recovered, covering the period between the commencement of hydraulic fracturing and the implementation of the approved permit for the disposal of produced water under NPS requirements:

(h) Continuous monitoring records of annulus pressure at the bradenhead and other annular pressures that document pressures before, during, and after injection operations. You must submit a signed certification that wellbore integrity was maintained throughout the operation.
