   (a) If the person’s alcohol concentration was less than 0.15, or if for reasons other than the person’s refusal to take a test offered under RCW 46.20.308 there is no test result indicating the person’s alcohol concentration:

   (i) Where there has been no prior offense within seven years, be suspended or denied by the department for ninety days;

   (ii) Where there has been one prior offense within seven years, be revoked or denied by the department for two years; or

   (iii) Where there have been two or more prior offenses within seven years, be revoked or denied by the department for three years;

   (b) If the person’s alcohol concentration was at least 0.15:

   (i) Where there has been no prior offense within seven years, be revoked or denied by the department for one year;

   (ii) Where there has been one prior offense within seven years, be revoked or denied by the department for nine hundred days; or

   (c) If by reason of the person’s refusal to take a test offered under RCW 46.20.308, there is no test result indicating the person’s alcohol concentration:

   (i) Where there have been no prior offenses within seven years, be revoked or denied by the department for two years;

   (ii) Where there has been one prior offense within seven years, be revoked or denied by the department for three years; or

   (iii) Where there have been two or more previous offenses within seven years, be revoked or denied by the department for four years.

   The department shall grant credit on a day-for-day basis for any portion of a suspension, revocation, or denial already served under this subsection for a suspension, revocation, or denial imposed under RCW 46.20.3101 arising out of the same incident.

   For purposes of this subsection (9), the department shall refer to the driver’s record maintained under RCW 46.52.120 when determining the existence of prior offenses.

   (11)(a) In addition to any nonsuspendable and nondeferrable jail sentence required by this section, whenever the court imposes less than one year in jail, the court shall also suspend but shall not defer a period of confinement for a period not exceeding five years. The court shall impose conditions of probation that include: (i) Not driving a motor vehicle within this state without a valid license to drive and proof of financial responsibility for the future; (ii) not driving a motor vehicle within this state while having an alcohol concentration of 0.08 or more within two hours after driving; and (iii) not refusing to submit to a test of his or her breath or blood to determine alcohol concentration upon request of a law enforcement officer who has reasonable grounds to believe the person was driving or was in actual physical control of a motor vehicle within this state while under the influence of intoxicating liquor. The court may impose conditions of probation that include nonrepetition, installation of an ignition interlock device on the probationer’s motor vehicle, alcohol or drug treatment, supervised probation, or other conditions that may be appropriate. The sentence may be imposed in whole or in part upon violation of a condition of probation during the suspension period.

   (b) For each violation of mandatory conditions of probation under (a)(i), (ii), or (iii) of this subsection, the court shall order the convicted person to be confined for thirty days, which shall not be suspended or deferred.

   (c) For each incident involving a violation of a mandatory condition of probation imposed under this subsection, the license, permit, or privilege to drive of the person shall be suspended by the court for thirty days or, if such license, permit, or privilege to drive already is suspended, revoked, or denied at the time the finding of probation violation is made, the suspension, revocation, or denial then in effect shall be extended by thirty days. The court shall notify the department of any suspension, revocation, or denial or any extension of a suspension, revocation, or denial imposed under this subsection.

   (b) The offender does not reside in the state of Washington; or

   (c) The court determines that there is reason to believe that the offender would violate the conditions of the electronic home monitoring penalty.

   Whenever the mandatory minimum term of electronic home monitoring is waived, the court shall state in writing the reason for granting the waiver and the facts upon which the waiver is based, and shall impose an alternative sentence with similar punitive consequences. The alternative sentence may include, but is not limited to, additional jail time, work crew, or work camp.

   Whenever the combination of jail time and electronic home monitoring or alternative sentence would exceed three hundred sixty-five days, the offender shall serve the jail portion of the sentence first, and the electronic home monitoring or alternative portion of the sentence shall be reduced so that the combination does not exceed three hundred sixty-five days.

   (13) An offender serving a sentence under this section, whether or not a mandatory minimum term has expired, may be granted an extraordinary medical placement by the jail administrator subject to the standards and limitations set forth in *RCW 9.94A.728(4).
