¶1 The issue in this case is whether a sentencing court may impose an exceptional sentence downward if the judge finds the multiple offense policy of RCW 9.94A-.589 results in a presumptive sentence that is clearly excessive in light of the purposes of the Sentencing Reform Act of 1981 (SRA), chapter 9.94A RCW. We need look only to the plain language of the SRA to conclude the sentencing court has such discretion.
Yu, J.Facts and Procedural History
f 2 This case results from Jason Allen Graham’s methamphetamine-induced shooting spree in January 2002. At about 1:00 a.m., a police officer stopped the vehicle Graham was driving. Over the next several minutes, Graham used an AK-47 to fire at six different police officers during a foot chase through downtown Spokane. Fortunately, he was the only person physically injured in the incident. Graham was convicted by a jury in 2003 of 10 offenses, including 6 “serious violent offenses” for sentencing purposes under the SRA. RCW 9.94A.030(45). He received an aggregate sentence of 1,225.5 months, the result of an increased *881offender score and consecutive sentences in accordance with RCW 9.94A.589(l)(b), in addition to several firearm enhancements.
¶3 The Court of Appeals affirmed the original judgment and sentence, but we granted review and remanded to the Court of Appeals to reconsider the firearm enhancements in light of State v. Williams-Walker, 167 Wn.2d 889, 225 P.3d 913 (2010). State v. Graham, 169 Wn.2d 1005, 234 P.3d 210 (2010). On reconsideration, the Court of Appeals vacated Graham’s sentence and remanded for resentencing. State v. Graham, noted at 163 Wn. App. 1011 (2011), review denied, 173 Wn.2d 1011 (2012).
¶4 At resentencing Graham asked for an exceptional sentence downward of 25 years. He argued RCW 9.94A-.535(l)(g) — the “multiple offense policy” mitigating factor— permitted both a departure from the standard range and imposition of concurrent sentences. The original sentencing judge expressed regret at the presumptive sentencing range for Graham’s serious violent offenses. The judge stated on the record that there was no authority to impose an exceptional sentence:
And quite frankly, in my mind [the presumptive sentence is] an awful lot of time for this. . . .
... I don’t agree with this sentence. I don’t agree with it. I’m not suggesting that you don’t deserve a punishment. . . . But without some other mitigating circumstance, my hands are tied. Again, I don’t write the laws; the legislature writes the laws. And this type of a scenario was something that was anticipated by the law-writers when they wrote the law. So I don’t believe that I have a choice but to sentence you within the standard sentence range. It is going to be a low-end sentence, however.
Verbatim Report of Proceedings at 28-29. The judge imposed a sentence at the low end of the standard range for each serious violent offense to run consecutively, for a total sentence of 82.1 years. Graham again appealed his sentence, and the Court of Appeals affirmed. State v. Graham, 178 Wn. App. 580, 314 P.3d 1148 (2013). We granted review *882to determine whether RCW 9.94A.535(l)(g) permits exceptional sentences for multiple serious violent offenses scored under RCW 9.94A.589(l)(b). State v. Graham, 180 Wn.2d 1013, 327 P.3d 55 (2014).
Analysis
¶5 As with all statutes, we interpret the SRA de novo to discern and implement the legislature’s intent. State v. Jones, 172 Wn.2d 236, 242, 257 P.3d 616 (2011). We look first to the plain language, which, if unambiguous, ends the inquiry. State v. Armendariz, 160 Wn.2d 106, 110, 156 P.3d 201 (2007). We enforce the plain meaning of statutes. If there is no plain meaning and the language is ambiguous, we may glean the statute’s intent from its legislative history. Id. at 110-11.
A
¶6 Under the SRA, a sentencing court generally must impose a sentence within the standard sentencing range. RCW 9.94A.505(2)(a)(i). However, the SRA authorizes a departure from the standard range in some circumstances. See RCW 9.94A.535. Specifically, .535(1) lists mitigating circumstances that a court might rely on depending on the facts of the particular case. The one at issue here is .535(l)(g):
The court may impose an exceptional sentence below the standard range if it finds that mitigating circumstances are established by a preponderance of the evidence. The following are illustrative only and are not intended to be exclusive reasons for exceptional sentences.
. . . The operation of the multiple offense policy of RCW 9.94A.589 results in a presumptive sentence that is clearly excessive in light of the purpose of this chapter, as expressed in RCW 9.94A.010.
*883The “multiple offense policy of RCW 9.94A.589” that .535(l)(g) references contains five subsections. Those relevant in this case are subsections (l)(a) and (l)(b), which advise sentencing courts when sentences for multiple current offenses are presumed to run concurrent or consecutive to one another.
¶7 The State argues “the multiple offense policy of RCW 9.94A.589” does not include multiple serious violent offenses under .589(l)(b) because its sole purpose “is to permit consecutive sentences in an otherwise concurrent mandate.” Suppl. Br. at 5. The State contends the legislature intended to foreclose exceptional sentences for serious violent offenses. So we must decide if .535(l)(g) applies equally to subsections (l)(a) and (l)(b) of .589.
B
¶8 We need look only to .535(l)(g)’s plain meaning to conclude the legislature considered exceptional sentences possible for some serious violent offenses. There is no textual support for the State’s position that the phrase “multiple offense policy,” as it appears in .535(l)(g), refers only to multiple violent and nonviolent offenses and not to multiple serious violent offenses. The State does not explain why .535(l)(g)’s broad reference to “RCW 9.94A.589” means only subsection (l)(a). All five subsections in .589 deal with sentencing multiple offenses. The legislature knows how to cite specific subsections and twice cited subsection .589(l)(a) specifically, including within the SRA. See RCW 61.34.030; RCW 9.94A.525(5)(a)(i). The legislature also separately identified subsections .589(1) and (2) elsewhere in the text of .535, implying its failure to separately identify subsections .589(l)(a) and (b) was a deliberate policy choice. RCW 9.94A.535.
¶9 We found the plain text of .535 dispositive in In re Personal Restraint of Mulholland, 161 Wn.2d 322, 166 P.3d 677 (2007). There the defendant sought concurrent sen*884tences for six counts of first degree assault, a serious violent offense under the SRA. The State similarly argued .535(l)(g) did not apply because .589(l)(b) mandated consecutive sentences for all serious violent offenses. Id. at 328-29. We unanimously concluded the sentencing judge could rely on .535(l)(g) to impose concurrent sentences:
[T]he State’s argument fails because it pays too little heed to the plain language of RCW 9.94A.535. . . . Because [,535(l)(g)] does not differentiate between subsections (l)(a) and (l)(b) [of .589], it can be said that a plain reading of the statute leads inescapably to a conclusion that exceptional sentences may be imposed under either subsection of RCW 9.94A.589(1).
Id. at 329-30. Mulholland is controlling, and this case does not provide a factual or legal basis to reject or depart from our prior interpretation of .535.
f 10 We find additional support for our holding elsewhere in the SRA. Unlike sentences for other crimes, the legislature has not expressly revoked discretion to impose exceptional sentences for serious violent offenses. For example, exceptional sentences downward are not available for persistent offenders, offenses with mandatory minimums, or some sex offenses. See RCW 9.94A.507(3)(c)(ii), .540(1), .570. Sentencing enhancements, the lengths of which the sentencing judge cannot modify, also increase some sentences even if facts permit a departure from the standard range for the underlying offense. RCW 9.94A.533. No similar provisions bar exceptional sentences for serious violent offenses scored under .589(l)(b).
¶11 The only rationale offered by the State and the unpublished cases cited by the Court of Appeals is the legislature’s intent that serious violent offenses carry more severe punishment than other crimes. These authorities often rely on a single sentence in Professor David Boerner’s seminal treatise. David Boerner, Sentencing in Washington § 9.12(e) at 9-32 (1985). But if Professor Boerner’s comments on the subject are read in context, he suggests only that the legislature constructed the SRA to signal excep*885tional sentences for multiple offenses “ought to be rare.” Id. This is accomplished not by prohibiting exceptional sentences for multiple serious violent offenses altogether, but by limiting them for presumptive range sentences that are “clearly excessive,” RCW 9.94A.535(l)(g), and where the exceptional sentence is supported by “substantial and compelling reasons.” RCW 9.94A.535. These constrictions refute the State’s admonition that Mulholland has stripped .589(l)(b) of practical effect or that we risk returning to the pre-SRA era of disparate sentencing.
f 12 We take this opportunity to reaffirm that a sentencing judge may invoke .535(l)(g) to impose exceptional sentences both for multiple violent and nonviolent offenses scored under ,589(l)(a) and for multiple serious violent offenses under .589(l)(b).
C
¶13 The State challenges our holding in Mulholland in two ways. First, it argues we erred in Mulholland by creating a rule contrary to the legislature’s intent. But we simply construed the unambiguous language of .535(l)(g), which is the best evidence of legislative intent. And the legislature has indicated its approval of our interpretation by not amending .535 in the seven years since our decision. Hangman Ridge Training Stables, Inc. v. Safeco Title Ins. Co., 105 Wn.2d 778, 789, 719 P.2d 531 (1986).
¶14 Second, the State suggests Mulholland allows only exceptional concurrent sentences for serious violent offenses and does not permit downward departures from the standard sentencing range. Our case law compels a different conclusion. In State v. Batista, 116 Wn.2d 777, 784-85, 808 P.2d 1141 (1991), we considered the scope of former RCW 9.94A.390(2)(f) (1988), which allowed upward departures when “the multiple sentencing policy of RCW 9.94A-.[589] results in a presumptive sentence that is clearly too lenient in light of the purpose of [the SRA].” We held the *886sentencing judge could use this aggravator to impose two types of exceptional sentences for offenses scored using .589(l)(a). “If a presumptive sentence is clearly too lenient, this problem could be remedied either by lengthening concurrent sentences, or by imposing consecutive sentences.” Id. at 785-86.
f 15 The form of current .535(l)(g) mirrors the language of former RCW 9.94A.390(2)(f) at issue in Batista. Both cure the same sentencing concern. The legislature “adopted [these] parallel” provisions to address “the potential that its multiple offense policy could operate to produce presumptive sentence ranges inconsistent with the purposes of the [SRA].” Boerner, supra, § 9.12(e) at 9-31 (footnote omitted). Following Batista’s rationale, we hold .535(l)(g) empowers a sentencing judge to reduce a “clearly excessive” sentence by lessening sentences for the offenses and/or by imposing concurrent sentences.
f 16 The State offers no persuasive policy reason to limit .535(l)(g) to imposing concurrent standard range sentences for serious violent offenses. The legislature recognized it could not craft a standard range that could account for all factual variations underlying offenses and offenders. It adopted .535 as a safety valve. State v. Oxborrow, 106 Wn.2d 525, 530, 723 P.2d 1123 (1986). Since concurrent sentences are sometimes necessary to remedy injustices caused by the mechanical application of grids and ranges, as we recognized in Mulholland, there is no reason why downward departures from the standard range cannot accomplish the same goal.
D
¶17 Finally, Graham asks us to clarify the factual finding a sentencing judge must make to invoke the multiple offense policy mitigating factor of .535(l)(g). We decline to do so because we think the statute is also clear on that point. It directs the judge to consider if the presump*887tive sentence “is clearly excessive in light of the purpose of this chapter, as expressed in RCW 9.94A.010.” RCW 9.94A-.535(l)(g) (emphasis added). RCW 9.94A.010 lists seven policy goals the legislature intends the SRA to advance:
(1) Ensure that the punishment for a criminal offense is proportionate to the seriousness of the offense and the offender’s criminal history;
(2) Promote respect for the law by providing punishment which is just;
(3) Be commensurate with the punishment imposed on others committing similar offenses;
(4) Protect the public;
(5) Offer the offender an opportunity to improve himself or herself;
(6) Make frugal use of the state’s and local governments’ resources; and
(7) Reduce the risk of reoffending by offenders in the community.
Sentencing judges should examine each of these policies when imposing an exceptional sentence under .535(l)(g).
Conclusion
¶18 We hold RCW 9.94A.535(l)(g) allows an exceptional sentence for multiple current serious violent offenses scored under RCW 9.94A.589(l)(b) that is achieved by departing downward from the standard ranges for the offenses and/or by running sentences concurrently. We reverse the Court of Appeals and remand for resentencing consistent with this opinion. We take no position on whether Graham’s sentence is “clearly excessive” under .535(l)(g) or on the virtues of his 25-year sentence recommendation, as those issues are properly left for the sentencing judge.
