Conditions of post-release supervision.

Upon release from the underlying term of imprisonment, the person shall be furnished with a written statement setting forth the conditions of post-release supervision in sufficient detail to provide for the person's conduct and supervision. 4. Revocation of post-release supervision. An alleged violation of any condition of post-release supervision shall be initiated, heard and determined in accordance with the provisions of subdivisions three and four of section two hundred fifty-nine-i of the executive law. 5. Calculation of service of period of post-release supervision. A period or periods of post-release supervision shall be calculated and served as follows:

(a) A period of post-release supervision shall commence upon the person's release from imprisonment to supervision by the department of corrections and community supervision and shall interrupt the running of the determinate sentence or sentences of imprisonment and the indeterminate sentence or sentences of imprisonment, if any. The remaining portion of any maximum or aggregate maximum term shall then be held in abeyance until the successful completion of the period of post-release supervision or the person's return to the custody of the department of corrections and community supervision, whichever occurs first.

(b) Upon the completion of the period of post-release supervision, the running of such sentence or sentences of imprisonment shall resume and only then shall the remaining portion of any maximum or aggregate maximum term previously held in abeyance be credited with and diminished by such period of post-release supervision. The person shall then be under the jurisdiction of the department of corrections and community supervision for the remaining portion of such maximum or aggregate maximum term.

(c) When a person is subject to two or more periods of post-release supervision, such periods shall merge with and be satisfied by discharge of the period of post-release supervision having the longest unexpired time to run; provided, however, any time served upon one period of post-release supervision shall not be credited to any other period of post-release supervision except as provided in subdivision five of section 70.30 of this article.

(d) When a person is alleged to have violated a condition of post-release supervision and the department of corrections and community supervision has declared such person to be delinquent: (i) the declaration of delinquency shall interrupt the period of post-release supervision; (ii) such interruption shall continue until the person is restored to post-release supervision; (iii) if the person is restored to post-release supervision without being returned to the department of corrections and community supervision, any time spent in custody from the date of delinquency until restoration to post-release supervision shall first be credited to the maximum or aggregate maximum term of the sentence or sentences of imprisonment, but only to the extent authorized by subdivision three of section 70.40 of this article. Any time spent in custody solely pursuant to such delinquency after completion of the maximum or aggregate maximum term of the sentence or sentences of imprisonment shall be credited to the period of post-release supervision, if any; and (iv) if the person is ordered returned to the department of corrections and community supervision, the person shall be required to serve the time assessment before being re-released to post-release supervision. In the event the balance of the remaining period of post-release supervision is six months or less, such time assessment may be up to six months unless a longer period is authorized pursuant to subdivision one of this section. The time assessment shall commence upon the issuance of a determination after a final hearing that the person has violated one or more conditions of supervision. While serving such assessment, the person shall not receive any good behavior allowance pursuant to section eight hundred three of the correction law. Any time spent in custody from the date of delinquency until return to the department of corrections and community supervision shall first be credited to the maximum or aggregate maximum term of the sentence or sentences of imprisonment, but only to the extent authorized by subdivision three of section 70.40 of this article. The maximum or aggregate maximum term of the sentence or sentences of imprisonment shall run while the person is serving such time assessment in the custody of the department of corrections and community supervision. Any time spent in custody solely pursuant to such delinquency after completion of the maximum or aggregate maximum term of the sentence or sentences of imprisonment shall be credited to the period of post-release supervision, if any.

(e) Notwithstanding paragraph (d) of this subdivision, in the event a person is sentenced to one or more additional indeterminate or determinate term or terms of imprisonment prior to the completion of the period of post-release supervision, such period of post-release supervision shall be held in abeyance and the person shall be committed to the custody of the department of corrections and community supervision in accordance with the requirements of the prior and additional terms of imprisonment.

(f) When a person serving a period of post-release supervision is returned to the department of corrections and community supervision pursuant to an additional consecutive sentence of imprisonment and without a declaration of delinquency, such period of post-release supervision shall be held in abeyance while the person is in the custody of the department of corrections and community supervision. Such period of post-release supervision shall resume running upon the person's re-release.
