Opinion by
Judge Colins,This is an appeal by the Commonwealth of Pennsylvania, Department of Environmental 'Resources (DER) from an adjudication of the Environmental Hearing Board (EHB). The EHB held that DER had improperly forfeited two bonds issued to Coal Hill Contracting Company, Incorporated (Coal Hill) by Clearfield Bank and Trust Company (Clearfield Bank) as surety to the Commonwealth of Pennsylvania to guarantee compliance by Coal Hill with the requirements of the Surf ace Mining Conservation and Reclamation Act (SMCRA).1
• From 1974 to Í978, Coal Hill was authorized* under six permits issued pursuant to SMCRA, to conduct surface coal mining operations in Lawrence and Bradford Townships in Clearfield County, Pennsylvania. At issue in the instant case are mining permits 1470-1, 1470-1A, 1470-1 (A2), and 1470-1(A3)2 and Í470-3, *156granted to Coal Hill for its operations in Bradford Township.
As a condition of obtaining mining permits 1470-2 and 1470-2A, Coal Hill submitted to DEB a bond in the amount of Twenty-three Thousand Dollars ($23,000.00). The terms of that bond provide that liability shall accrue in proportion to the area of land affected by surface mining at the rate of Five Hundred Seventy-five Dollars ($575.00) per acre or part thereof. To obtain mining permit 1470-2(A2), Coal Hill ¡submitted a Five Thousand Dollar ($5,000.00) bond to DEB which ¡stated 'that liability shall accrue in proportion to the area of land affected by surface mining at the rate of Five Hundred Dollars ($500.00) per acre or part thereof. Finally, in order to receive permit 1470-3, Goal Hill submitted to DEB Surety Bond No. 558E2324 in the amount of Seven Thousand One Hundred Dollars ($7,100.00). Surety Bond No. 558E2324 provides that liability upon the bond shall accrue in proportion to the area affected by surface mining at the rate of One Thousand Dollars ($1,000-.00) per acre or part thereof. All of the ¡above¡ bonds *157stale that in no ease shall such liability be for an amount less than Five Thousand Dollars ($5,000.00).
Mining permits 1470-2, 1470-2A, 1470-2 (A2),3 .and 1470-3 were issued for 20 acres, 20 acres, 10 acres, and 7.1 acres respectively, all of which were worked by Coal Hill.4 No reclamation work was completed in the affected areas pertaining to permits 1470-2 and 1470.73, However, all of the affected acres associated, with permits! 1470-2A and 1470-2(A2) have been restored;
Notice of the forfeitures of the bonds submitted for permits 1470-2, 1470-2A, 1470-2(A2), and 1470-3 was sent to Coal Hill on July 9, 1982. Additionally, Coal Hill had also failed to restore a three-acre area *158adjacent to the Bradford Township site, not covered by a mining permit. Goal Hill appealed the forfeitures to the EHB. On August 6, 1984, the EHB sustained the forfeiture of .the bonds associated with permits 1470-2 and 1470-3, 'but concluded that HER had abused its discretion by forfeiting the bonds submitted as a condition of obtaining mining permits 1470-2A and 1470-2(A2).5 On August 27, 1984, DER petitioned the EHB for reconsideration of its decision, and likewise, on 'September 5, 1984, petitioned this Court for a review of the decision. The petition for reconsideration was .subsequently denied by the EHB on September 7,1984.
Our .scope of review is limited to a determination of whether constitutional rights were violated, whether an error of law was committed, or whether the findings of fact are supported by substantial evidence. Lucas v. Department of Environmental Resources, 53 Pa. Commonwealth Ct. 598, 420 A.2d 1 (1980).
The bonds state in pertinent part that:
NOW THE CONDITION OF THIS OBLIGATION is such that if the principal shall faithfully perform all the requirements of (1) Act 418, (2) the Act of Assembly approved June 22, 1937, P.L. 1987, as amended, known as ‘The *159Clean Streams Law’6 (Act 394), (3) the applicable rules and regulations promulgated thereunder and (4) the provisions and conditions of the permits issued thereunder and designated in this bond (all of which are hereafter referred to as daw’), then this obligation shall be null and void, otherwise to be and remain in full force and effect in accordance with the provisions of the law. (Emphasis added.)
It is important to note that the bonds became part of the permits issued by LEE. The purpose of the bonds is to reimburse the ¡Commonwealth for damages which may arise from non-compliance with the requirements of SMECA insofar as the non-compliance relates to the permitted area.
Petitioner posits that the EHB should be reversed due to its conclusion that the bonds in question were “mere contracts” rather than “¡statutory bonds” of a “penal nature”. This argument misses the point. All bonds required by statute are “statutory” in'nature, such that the contract between the parties may be controlled, in part, by legislative intent. The bonds in the instant matter can certainly be considered as “penal” in nature, as LEE need not prove actual damages where an operator has breached the condition of the surety. See American Casualty Company of Reading v. Department of Environmental Resources, 65 Pa. Commonwealth Ct. 223, 234, 441 A.2d 1383, 1388-1389 (1982). The characterization of the bonds does not control; but rather .the areas covered by the bonds.
Petitioner further argues ¡that it can forfeit all of the bonds submitted iby Coal Hill because Coal Hill has mined off the permitted area and has refused to complete reclamation of this effected area.
*160Wé hold .that each bond was issued as part of a specific permit and not as an umbrella to' cover all mining' being performed by the operator and as such, we affirm the order of the EHB.
•25 Pa. Code §86.1 defines surface mining activities to include “all [those] activities in which the land surface has been or is disturbed as a result of or incidental to surface mining operations. . . .” (Emphasis added.)
We interpret the above definition to include those circumstances where the operator accidently or intentionally goes beyond the geographical boundaries of the area specified in the permit. The .three acres in the "instant case, which were affected by 'Coal Hill, clearly fall within the above definition. However, the ■ off-permit'mining and/or the failure to reclaim this area does not justify the forfeiture of all the bonds posted for the other permitted areas. It is more appropriate that a portion of the bond or the entire bond be- forfeited to complete reclamation in a non-permitted area only when the permitted area is adjacent -to or contiguous to the affected off-permit area, or is one in which the ecological harm may be traced directly to the specifically permitted area.
To espouse a policy that allows forfeiture of bonds when -the ecological damage occurs on a totally unrelated area amounts to an abuse of discretion by DEE. Pennsylvania is a vast state with many coal companies operating in various counties of the Commonwealth. It is not uncommon for a coal company 'to be conducting' mining operations in several counties simultaneously. To hold a company’s bonds subject •to forfeiture in County “A” for unrelated operations in county “B ’■’ would place' an -intolerable burden upon the surety and as such act as a deterrent to the issuance of any mining related surety. It would .become *161actuarially impossible fox surety companies and bonding agencies ¡to issue bonds knowing that they may be forfeited for damages caused by totally unrelated mining operations in totally unrelated areas.
In the case at bar, bond No. 558E2324 was posted fox the permitted ¡area adjacent to the three acres mined without a permit. Bond No. 558E2324 was submitted as a condition of receiving permit 1470-3. This entire bond has been forfeited because ¡Goal Hill failed to reclaim the acreage associated with permit 1470-3. The amount of the bond forfeited is not sufficient to complete reclamation of the contiguous non-permitted acreage. Despite this, we must ¡affirm the: EHB’s ruling that bonds associated with permits 1470-2A and 1470-2(A2) may not be forfeited either since these bonds were not posted for the affected off-permit area.
A proper remedy for DEB to pursue against Coal Hill for its off permit mining activities is contained in Section 18.4 of the SMCBA, 52 P.S. §1396.22 — the assessment of a civil penalty. See Western Hickory Coal Company v. Department of Environmental Resources, 86 Pa. Commonwealth Ct. 562, 485 A.2d 877 (1984).7
With respect to permits 1470-2 and 1470-3, DEB Mine Inspector Forcy testified that no reclamation had been accomplished. Accordingly, the entire per acre liability on these bonds was. forfeited; being Eleven Thousand Five Hundred Dollars ($11,500.00) for permit 1470-2 and ¡Seven Thousand One Hundred Dollars ($7,100.00) for permit 1470-3. Coal Hill introduced no evidence to counter this, testimony. Inspector Forcy, however, stated that the area Of 1470-2A and 1470-2(A2) is restored and planted and in good condition.
*162’ The EHB properly concluded that BEE had not met its burden of proof that Coal Hill failed to comply with ¡the applicable ¡statutes, rules or regulations with regard to the acreage covered by permits 1470-2A and ;1470-2(A2) and that BEE had abused its discretion in .forfeiting the bonds associated with permits 1470-2A .and 1470-2 (A2).
Accordingly, the order of the EHB is affirmed.

*156The terms of surety bond No. 217B6839 and surety bond No. 218B2244 provide that liability shall accrue in proportion to the area of land affected by surface mining at the rate of Five Hundred Seventy-five Dollars ($575.00) per acre or part thereof.
On October 14, 1975, Coal Hill assigned to DER savings certificate No. 977 in the amount of Two Thousand Four Hundred Dollars ($2,400.00) as a condition of obtaining mining permit 585-5 (A3). The savings certificate was drawn on the Clearfield Bank and Trust Company. DER issued mining permit 1470-1 (A2) to Coal Hill on October 27, 1978; a special permit transferred the liability and obligation under savings certificate No. 977 which had previously accrued by C. A. Ogden Company under withdrawn mining permit 585-5 (A3). The terms of the collateral bond submitted as a condition of obtaining- mining permit 585-5(A3) (now permit 1470-1(A2) affected by surface mining at the rate of Five Hundred Dollars ($500.00) per acre or part thereof.
On March 17, 1976, Coal Hill assigned to DER savings certificate No. 879 in the amount of Twenty Three Thousand Dollars ($23,000.00) as a condition of obtaining mining permit 585-6. The savings certificate was drawn on Clearfield Bank. DER issued mining permits 1470-2 and 1470-2A to Ooal Hill on October 30, 1978; a special condition of both permits transferred the liability and obligation under the bond associated with permit 585-6 which had previously accrued to C. A. Ogden Company.
On March 17, 1976, Coal Hill assigned to DER savings certificate No. 976 in the amount of Five Thousand Dollars ($5,000.00) as a condition of obtaining mining permit 585-6A. The savings certificate was drawn on Clearfield Bank. DER issued mining permit 1470-2 (A2) to Coal Hill on October 30, 1978; a special permit condition transferred the liability and obligation under the bond associated with permit 585-6A which had previously been incurred by C.

Mining permit 1470-1 was issued for 20 acres; 10.2 acres were affected by Coal Hül. Coal Hill graded six acres on permit 1470-1 to approximate original contour and accomplished no reclamation of the remaining 4.2 affected acres. • • '
• ■ Mining-permit 1470-1A was issued for 27.2 acres; 17.3 were affected by Coal Hill. Coal Hill graded six acres on permit 1470-1A to ‘ approximate original contour and accomplished no reclamation of the remaining 11.3 affected acres.
Mining permit 1470-1 (A2) was issued for 4.8 acres; 0.5 acres were affected by Coal Hill. No reclamation of the 0.5 affected acres was ¿ceomplished.
The EHB concluded that DER had met its burden of proof that Coal Hill- failed to comply with the applicable statutes, rules or regulations with regard to all of the affected acreage covered by permits 1470-1, 1470-1A, and 1470-1 (A2). The EHB further concluded that for each of the bonds associated with the above permits, with the exception of permit 1470-1 (A2), forfeiture was appropriate in an amount equal to the number of acres affected and not reclaimed multiplied by the per acre liability specified in the applicable bonds. Forfeiture of the entire amount of the bond associated with permit 1470-1 (A2) is appropriate; the minimum liability condition of the bond is applicable where the forfeiture would otherwise be for an amount less than Five Thousand Dollars ($5,000.00).
