CONCURRING AND DISSENTING OPINION BY
Judge LEAVITT.The majority adopts the reasoning of the trial court in its entirety, thereby holding that only Section 2 of the interest arbitration award (Award) violates Green-ville’s Act 47 Recovery Plan. While I agree with that part of the trial court’s decision, I disagree with the trial court’s interpretation of Sections 4 and 14 of the Award as consistent with the Recovery Plan. Therefore, I must respectfully dissent.
As noted by the majority, Section 252 of Act 47 states that “[a] collective bargaining agreement or arbitration settlement executed after the adoption of a [financial recovery] plan shall not in any manner *703violate, expand or diminish [the financial recovery plan’s] provisions.” 53 P.S. § 11701.252. This Court has previously interpreted Section 252 of Act 47 to mean that once a recovery plan is adopted, no collective bargaining agreement adopted thereafter may be inconsistent with the recovery plan’s provisions. Pittsburgh Fire Fighters, Local No. 1 v. Yablonsky, 867 A.2d 666, 668 (Pa.Cmwlth.2005). In the context of an Act 111 bargaining dispute, this Court has explained the operation of Section 252 of Act 47 as follows:
Although Act 47 places limitations on the bargaining rights of parties, Act 111 still controls the procedure for resolution of bargaining disputes.... Act 111 sets forth the rights that unions ... have in the bargaining process; however, as a matter of legislative, rather than constitutional grace, the General Assembly may limit or contract the rights it has bestowed. Plans developed pursuant to Act 47 represent such a limitation.
Id. at 672. In short, any provision of an arbitration award that violates a provision of an Act 47 recovery plan must be stricken or modified to conform with the plan.
I agree with Greenville that Section 4 of the Award must be stricken or modified because it is inconsistent with Section 164 of the Recovery Plan.1 Section 4 of the Award provides, in pertinent part, as follows:
Longevity — The current longevity pay scale shall remain in effect for all Firefighters hired before January 1, 2006. The following steps shall be added to the existing longevity pay scale.
a. After 24 years $800
b. After 30 years $875
e. Full-time Firefighters hired on or after January 1, 2006 shall receive longevity payments as follows:
After 3 years $125
After 6 years $225
After 9 years $325
After 12 years $425
After 15 years $525
After 18 years $625
After 21 years $725
Reproduced Record at 698a (R.R. -). Section 164 of the Recovery Plan provides as follows:
Wages: While under Act 47 the base hourly wages and salary increases, if granted, shall not exceed the lesser of the Consumer Price Index (CPI) for the northwest Pennsylvania region or 3%. Distribution of these moneys among the various bargaining units shall be fair and equitable and shall generally be in proportion to the actual 2002 costs incurred for each bargaining unit. Use of these moneys could include one-time bonuses, wage adjustments or other means. Whatever the terms of future collective bargaining agreements, arbitration awards, etc., no back wages or other retroactive adjustment shall be made.
R.R. at 173a-174a (emphasis added). The trial court concluded that the longevity payments provided in Section 4 of the Award “are not wages” but, rather, are “more akin to a bonus.” Trial Court Opinion at 13.
The trial court’s rationale cannot stand. The language emphasized in Section 164 of the Recovery Plan plainly includes “onetime bonuses, wage adjustments or other *704means” as payments within the 3 percent maximum wage increase. Because the longevity payments will result in a wage increase for the firefighters in excess of 3 percent, Section 4 of the Award is inconsistent with Section 164 of the Recovery Plan. I believe the trial court erred in not striking or modifying Section 4 of the Award.
Greenville also contends that Section 14 of the Award must be stricken or modified because the minimum manning requirements it imposes are inconsistent with the elimination of such requirements in Section 173 of the Recovery Plan. Again, I agree.
Section 14 of the Award provides as follows:
Staffing and Safety — Addendum A will be replaced with the following:
In order to insure the safety of the members of the Greenville Fire Department, the Borough will comply with the following staffing requirements:
The Borough will maintain an apparatus staffing level, excluding the Chief, of two (2) Firefighters during the term of this Agreement. No Greenville Fire Department fire-apparatus will respond to any fire suppression call from the station with fewer than two (2) Firefighters, either two Firefighters on one (1) piece of fire-fighting apparatus or one (1) Firefighter on each of two pieces of fire-fighting apparatus. The Borough may use a Relief Firefighter to fill one of the two Firefighter positions on occasions where a full-time Firefighter utilizes vacation, sick, training or holiday leave, subject to the restrictions contained in the Relief Firefighter provision of this Award.
R.R. at 700a (emphasis added). Section 173 of the Recovery Plan provides as follows:
Elimination of Minimum Manning: Any provision of any collective bargaining agreement between the borough and any of its unions concerning minimum manning requirements for any particular bargaining unit, shift, platoon, job classification, specialization, or position shall be eliminated. The borough shall have the sole right to determine the number of personnel employed and utilized by the borough. Further, the borough shall have the right to layoff any employees for economic or any other reasons, without limitation.
R.R. at 176a (emphasis added). The trial court concluded because Section 173 does not contain the words “firefighting apparatus” it did not bar the Award’s minimum manning requirements for a firefighting apparatus. I disagree with the trial court’s unduly narrow interpretation of Section 173 of the Recovery Plan.
Staffing for a responding apparatus, such as a fire truck, is certainly part of a “shift” or “position” and, arguably, is a “specialization” or “job classification,” and those terms are used in Section 173. Moreover, Section 173 provides Greenville with the exclusive right to determine the number of personnel employed and used by Greenville.2 I believe the trial court *705erred in not striking or modifying Section 14 of the Award.
I also write separately to address Local 1976’s assertion that Greenville should be precluded from invoking Section 252 of Act 47 because it has done so in a haphazard fashion. Local 1976 contends that an arbitration award between Greenville and its police department resulted in Greenville agreeing to a program of medical benefits that violates the Recovery Plan. Accordingly, Local 1976 argues that Greenville should be estopped from seeking to strike the Award in this case as inconsistent with the Recovery Plan. Local 1976’s argument lacks merit.
It is axiomatic that parties who have voluntarily negotiated and agreed to provisions in a collective bargaining agreement may not later attempt to avoid those provisions by claiming that they conflict with the law. Grottenthaler v. Pennsylvania State Police, 488 Pa. 19, 25, 410 A.2d 806, 809 (1980). However, this general rule does not extend to cases where a dispute is resolved by an arbitrator rather than through a collective bargaining agreement. Municipality of Monroeville v. Monroeville Police Department Wage Policy Committee, 767 A.2d 596 (Pa.Cmwlth.2001).3
Here, Greenville was forced by arbitration to give certain health insurance benefits to its police officers that were inconsistent with the Recovery Plan.4 The health insurance provision was not voluntarily negotiated by the parties. Additionally, Greenville does not challenge the health care contribution provision of the Award; rather, Greenville challenges the illegality of the minimum manning provision of the Award. Unlike the provision pertaining to firefighters, there is no minimum manning provision for the police in the Recovery Plan. Therefore, Greenville is not estopped or precluded from claiming that Section 14 of the Award must be stricken or modified as inconsistent with Section 173 of the Recovery Plan.
Based on the foregoing, I would affirm the trial court’s holding that Section 2 of the Award conflicted with the Recovery Plan and the trial court’s revision of that section. I would reverse the trial court with respect to Sections 4 and 14 of the Award because they are inconsistent with Greenville’s Recovery Plan.
President Judge LEADBETTER and Judge COHN JUBELIRER join in this concurring and dissenting opinion.. Greenville also contends that Section 4 of the Award is inconsistent with Section 179 of the Recovery Plan, which prohibits new benefits or expansion of benefits that have uncapped future costs. For the reasons stated by trial court, I agree that Section 4 of the Award is consistent with Section 179 of the Recovery Plan because the longevity payments provided in Section 4 are, in fact, capped.
. Section 241 of Act 47 permits a municipality to consider staffing level changes in a recovery plan, stating, in pertinent part, as follows:
... [A recovery plan] shall include any of the following factors which are relevant to alleviating the financially distressed status of the municipality:
(3) Possible changes in collective bargaining agreements and permanent and tem*705porary staffing level changes or changes in organization.
53 P.S. § 11701.241.
. For example, in Monroeville, the parties were in the process of negotiating a new collective bargaining agreement when a dispute arose regarding whether municipal pension benefits could exceed those provided for in the statute. The dispute was submitted for arbitration. The arbitrator decided that, despite the fact that they were inconsistent with the statutorily defined benefits, the disputed provisions could be included in the new collective bargaining agreement. This Court concluded that the municipality could challenge the illegality of the provision because it was part of the collective bargaining agreement not because of the parties’ negotiation but by decision of the arbitrator.
. An almost identical health care contribution provision was also awarded to Local 1976 in the Award.
