The General Laws are hereby amended by inserting after chapter 61B the following chapter:-

Chapter 61C: CLASSIFICATION AND TAXATION OF FOREST ECOSYSTEM LAND

Section 1. Definitions

“Certification”, approval of a forest ecosystem plan by a certified professional.

“Certified professional”, a certified forester, credentialed forest ecologist or designated land steward acting on behalf of an eligible planning agency or environmental organization.

“Contiguous land”, land separated from other land under the same ownership by a public or private way, waterway or an easement for water supply.

“Forest ecosystem”, land classified as forest ecosystem land pursuant to section 2.

“Forest ecovalue plan”, a completed copy of a form provided by the state and completed by an certified professional, and executed by the owner that provides for a 10 year program of maximal ecosystem services specific to the forest ecosystem land and accessory non-forested land, if applicable.

Section 2. Land not less than 10 contiguous acres in area shall be deemed to be forest ecosystem land that serves the public good through maximal ecosystem services if it has been retained in substantially a natural or wild condition for at least the previous 10 years and under a forest ecovalue plan established by a certified professional to maximize nature-based services such as carbon storage and sequestration, climate mitigation, biodiversity and ecosystem integrity.

Section 2A. The value of land classified under the provisions of this chapter shall be determined under section 38 of chapter 59 solely on the basis of its use. The board of assessors shall assess such land at valuations based upon the guidelines established under the provisions of chapter 58, but in no event shall such valuation exceed 10 per cent of its fair cash value as determined pursuant to chapter 59. The rate of tax applicable to forest ecosystem land shall be the lowest tax rate possible.

Section 3. Eligibility of land for valuation, assessment and taxation under this chapter shall be recertified every 10 years. Application therefor shall be submitted to the board of assessors of each city or town in which such land is situated not later than October first of the year preceding the tax year for which such valuation, assessment and taxation is being sought. Application shall be made on a form prescribed by the commissioner of revenue and provided for the use of applicants by said board of assessors. Such form shall provide for the reporting of information pertinent to the provisions of this chapter and for certification by the applicant that he or she will immediately notify the board of assessors in writing of any subsequent circumstance within his or her control or knowledge which may cause a change in use of the land covered by such form prior to October first next following. Any application submitted under this section and covering leased land shall be accompanied by a written statement signed by the lessee of his or her intent to use such land for the purposes set forth in said application. A certification by a landowner that the information set forth in his application is true may be prescribed by said commissioner to be in lieu of a sworn statement to that effect. An application so certified shall be considered as if made under oath and subject to the same penalties as provided by law for perjury.

Section 4. If a change in use of land maintained as forest ecosystem land as defined in section 1 occurs between October first and June thirtieth of the year preceding the renewal tax year, the board of assessors shall disallow or nullify the application filed under authority of section 3, and, after examination and inquiry, shall determine the full and fair value of said land under the valuation standard applicable to other land and shall assess the same according to such value. If, notwithstanding such change of use, the land is valued, assessed and taxed under the provisions of this chapter in the ensuing year, upon notice thereof said board shall enter an assessment and the amount of the increased tax resulting from such assessment, as an added assessment and tax against such land, for the particular year involved in the manner prescribed in section 75 of chapter 59. The amount of the added assessment shall be equal to the difference, if any, between the assessment imposed under this chapter and the assessment which would have been imposed had the land been valued and assessed as other land. The enforcement and collection of additional taxes resulting from any additional assessment so imposed shall be as provided by said chapters 59 and 60.

Section 5. In any city or town in which a program of revaluation of all property therein has been or shall be undertaken and completed in time to be reflected in the assessments for the next succeeding tax year but not in sufficient time to permit landowners to make application prior to October first of the year preceding the tax year for the valuation, assessment and taxation of their lands for the ensuing tax year on the basis of being maintained in forest ecosystem use, any such application filed with the board of assessors after October first and not more than 30 days following the mailing of the tax bill containing the new valuation shall be deemed to have been timely made for the tax year of the revaluation program, notwithstanding any provision of this chapter to the contrary. If such application is approved and the lands qualify for valuation, assessment and taxation as lands maintained for forest ecosystem use in the ensuing tax year, the portion of any tax assessed for such year which is in excess of the tax which would have been assessed on such lands had such application been timely made and approved shall be abated.

Section 6. An application for valuation, assessment and taxation of land under the provisions of this chapter shall be allowed or disallowed by the board of assessors of the city or town in which such land is located within 3 months of the filing thereof. An application for valuation, assessment and taxation of land under the provisions of this chapter shall be disallowed by the board of assessors of the city or town in which such land is located if, in their judgment such land, in whole or in part, does not qualify thereunder. If any board of assessors shall determine that any such application is submitted for the purpose of evading payment of full and proper taxes, such board shall disallow such application. The failure of a board of assessors to allow or disallow any such application within 3 months following the filing thereof, shall be deemed a disallowance of such application. The board of assessors shall, within 10 days of an allowance, or disallowance, send written notice of such allowance, or disallowance, by certified mail to the applicant and shall set forth therein the reason or reasons for disallowance together with a statement advising the applicant of his right to appeal therefrom as provided in section 14. In the case of a partial disallowance, the applicant shall be permitted to file an amendment to the original application.

With respect to the first application relating to a parcel of land which has been approved, and any subsequent such applications after a lapse of time when such land has not been valued, assessed and taxed under this chapter or after a change of record ownership of such land, the board of assessors shall forthwith cause to be recorded in the registry of deeds of the county or district in which the city or town is situated a statement of their action which shall constitute a lien upon the land covered by such application for such taxes as may be levied under the provisions of this chapter. The statement shall name the owner or owners of record and shall include a description of the land adequate for identification. Unless such a statement is recorded the lien shall not be effective with respect to a bona fide purchaser or other transferee without actual knowledge of such lien. Upon application of any record owner, such liens shall be released by the board of assessors with respect to any parcel of land as hereinafter provided upon the applicable facts being established by records, affidavits or otherwise.

All liens for conveyance tax under section 7 shall be released upon its being established that no conveyance or change of use by the owner at the time of such release will result in a conveyance tax under said section 7 or that any such taxes which have become due have been paid.

All liens for roll-back taxes under section 8, other than roll-back taxes based on change of use after the date of such release, shall be released upon its being so established that no roll-back taxes have become due or that any such taxes which have become due have been paid.

The board of assessors shall also have the power and authority to release any such liens to correct any errors or omissions. Any release under this section shall be recorded with the registry of deeds.

When any land which has been valued, assessed and taxed under this chapter ceases to be so valued, assessed and taxed the board of assessors shall forthwith record in the said registry of deeds a statement to that effect which shall include the name of the record owner or owners, the date when such land ceased to be so valued, assessed and taxed and a description of the land adequate for identification.

All recording fees paid under this chapter whether for statements of liens, certificates, releases or otherwise shall be borne by the owner of record of the land.

Section 7. Any forest ecosystem land which is valued, assessed and taxed under the provisions of this chapter, if sold for other use within a period of 10 years from the beginning of the fiscal year in which it was first so classified shall be subject to a conveyance tax applicable to the total sales price of such land, which tax shall be in addition to such taxes as may be imposed under any other provision of law. Said conveyance tax shall be at the following rate: 10 per cent if sold within the first 5 years of its being first so classified; and, 5 per cent if sold within the sixth through tenth year of its being first so classified. No conveyance tax shall be imposed under the provisions of this section following the end of the tenth year of its being first so classified. The conveyance tax shall be due and payable by the grantor at the time of transfer of the property by deed or other instrument of conveyance and shall be payable to the tax collector of the city or town in which the property is entered upon the tax list. In the case of taking by eminent domain, the value of the property taken shall be determined in accordance with chapter 79, and the amount of conveyance tax, if any, shall be added as an added value. If there is filed with the board of assessors an affidavit by the purchaser that the land is being purchased for forest ecosystem use, no conveyance tax shall be payable by the seller by reason of the sale, but if the land is not continued in that use for at least 5 consecutive years, the purchaser shall be liable for any conveyance tax that would have been payable on the sale as a sale for other use. The conveyance tax shall be assessed only on the portion of land whose use has changed. Notwithstanding the foregoing provisions, no conveyance tax shall be assessed if the land involved, or a lesser interest in the land, is acquired for a natural resource purpose by the city or town in which it is situated, by the commonwealth or by a nonprofit conservation organization, but if any portion of the land is sold for or converted to commercial, residential, or industrial use within 5 years of acquisition by a nonprofit conservation organization, the conveyance tax shall be assessed against the nonprofit conservation organization in the amount that would have been assessed at the time of acquisition of the subject parcel by the nonprofit conservation organization had such transaction been subject to a conveyance tax. The conveyance tax shall be assessed only on the portion of land whose use has changed.

Except with respect to eminent domain takings, this section shall not apply to the following: mortgage deeds; deeds to or by the city or town in which the land is located; deeds which correct, modify, supplement or confirm a deed previously recorded; deeds between husband and wife and parent and child when no consideration is received; tax deeds; deeds releasing any property which is a security for a debt or other obligation; deeds for division of property between owners without monetary consideration; foreclosures of mortgages and conveyances by the foreclosing parties; deeds made pursuant to a merger of a corporation or by a subsidiary corporation to a parent corporation for no consideration other than cancellation and surrender of capital stock of the subsidiary which do not change beneficial ownership; and property transferred by devise or other as a result of death. A nonexempt transfer subsequent to any exempt transfer or transfers shall be subject to the provisions of this section. Upon such nonexempt transfer the date of acquisition by the grantor, for purposes of this section, shall be deemed to be the date of the last preceding transfer not excluded by the foregoing provisions from application of this section; except that in the case of transfer by a grantor who has acquired the property from a foreclosing mortgagee the date of acquisition shall be deemed to be the date of such acquisition. If any tax imposed under this section should not be paid, the collector of taxes shall have the same powers and be subject to the same duties with respect to such taxes as in the case of the annual taxes upon real estate. The law in regard to the collection of the annual taxes, to the sale of land for the nonpayment thereof and to redemption therefrom shall apply to such taxes, so far as the same are applicable. Any classified forest ecosystem land which is valued, assessed and taxed under the provisions of this chapter, if changed by the owner thereof to another use within a period of 10 years from the date of its classification for forest ecosystem use by said owner, shall be subject to the conveyance tax applicable hereunder at the time of such change in use as if there had been an actual conveyance, and the value of such land for the purpose of determining a total sales price shall be fair market value as determined by the board of assessors of the city or town involved for all other property.

Notwithstanding this section, no conveyance tax imposed by this section will be assessed on land that meets the definition of forest land under section 1 of chapter 61 or the definition of agricultural land under sections 1 and 3 of chapter 61A or the definition of horticultural land under sections 2 and 3 of chapter 61A.

Section 8. Whenever land which is valued, assessed and taxed under this chapter no longer meets the definition of forest ecosystem use, it shall be subject to additional taxes, in this section called roll-back taxes, in the current tax year in which it is disqualified and in each of the 4 immediately preceding tax years in which the land was so valued, assessed and taxed, but the roll-back taxes shall not apply unless the amount of the taxes, as computed under this section, exceeds the amount, if any, imposed under section 7 and, in that case, the land shall not be subject to the conveyance tax imposed under said section 7. For each tax year, the roll-back tax shall be equal to the difference, if any, between the taxes paid or payable for that tax year in accordance with this chapter and the taxes that would have been paid or payable had the land been valued, assessed and taxed without regard to these provisions. Notwithstanding the foregoing provisions, no roll-back taxes shall be assessed if the land involved, or a lesser interest in the land, is acquired for a natural resource purpose by the city or town in which it is situated, by the commonwealth or by a nonprofit conservation organization, but if any portion of the land is sold or converted to commercial, residential, or industrial use within 5 years after acquisition by a nonprofit conservation organization, roll-back taxes shall be assessed against the nonprofit conservation organization in the amount that would have been assessed at the time of acquisition of the subject parcel by the nonprofit conservation organization had the transaction been subject to a roll-back tax. If, at the time during a tax year when a change in land use has occurred, the land was not then valued, assessed and taxed under the provisions of this chapter, then such land shall be subject to roll-back taxes only for such of the 5 immediately preceding years in which the land was valued, assessed and taxed thereunder. In determining the amount of roll-back taxes on land which has undergone a change in use, the board of assessors shall have ascertained the following for each of the roll-back tax years involved:

(a) the full and fair value of such land under the valuation standard applicable to other land in the city or town;

(b) the amount of the land assessment for the particular tax year;

(c) the amount of the additional assessment on the land for the particular tax year by deducting the amount of the actual assessment on the land for that year from the amount of the land assessment determined under clause (a); and,

(d) the amount of the roll-back tax for that tax year by multiplying the amount of the additional assessment determined under clause (c) by the general property tax rate of the city or town applicable for that tax year.

Interest on roll-back taxes shall be payable and shall be computed as simple interest at 5 per cent per annum. If the board of assessors determines that the total amount of the roll-back taxes to be assessed under this section, before the addition of any interest as provided for in the preceding paragraph, would be less than $10, no tax shall be assessed.

No roll-back tax imposed by this section will be assessed on land that meets the definition of forest land under section 1 of chapter 61, agricultural land under sections 1 and 3 of chapter 61A, or horticultural land under sections 2 and 3 of chapter 61A.

Land retained as open space as required for the mitigation of a development shall be subject to the roll-back taxes imposed by this section.

Section 9. Land taxed under this chapter shall not be sold for, or converted to, residential, industrial or commercial use while so taxed or within 1 year after that time unless the city or town in which the land is located has been notified of the intent to sell for, or to convert to, that other use.

The discontinuance of forest ecosystem use shall not, in itself, for the purposes of this section, be considered a conversion. Specific use of land for a residence for the owner, the owner's spouse or a parent, grandparent, child, grandchild, or brother or sister of the owner, or surviving husband or wife of any deceased such relative, or for living quarters for any persons actively employed full-time in the use and care of such land for forest ecosystem purposes, shall not be a conversion for the purposes of this section, and a certificate of the board of assessors, recorded with the registry of deeds, shall conclusively establish that particular use.

Any notice of intent to sell for such other use shall be accompanied by a statement of intent to sell, a statement of proposed use of the land, the location and acreage of land as shown on a map drawn at the scale of the assessors map in the city or town in which the land is situated, and the name, address and telephone number of the landowner.

Any notice of intent to sell for other use shall be accompanied by a certified copy of an executed purchase and sale agreement specifying the purchase price and all terms and conditions of the proposed sale, which is limited to only the property classified under this chapter, and which shall be a bona fide offer as described below.

Any notice of intent to sell for other use shall also be accompanied by any additional agreements or a statement of any additional consideration for any contiguous land under the same ownership, and not classified under this chapter, but sold or to be sold contemporaneously with the proposed sale.

For the purposes of this chapter, a bona fide offer to purchase shall mean a good faith offer, not dependent upon potential changes to current zoning or conditions or contingencies relating to the potential for, or the potential extent of, subdivision of the property for residential use or the potential for, or the potential extent of development of the property for industrial or commercial use, made by a party unaffiliated with the landowner for a fixed consideration payable upon delivery of the deed.

Any notice of intent to convert to other use shall be accompanied by a statement of intent to convert, a statement of proposed use of such land, the location and acreage of land as shown on a map drawn at the scale of the assessors map in the city or town in which the land is situated, the name, address and telephone number of the landowner and the landowner's attorney, if any.

The notice of intent to sell or convert shall be sent by the landowner by certified mail or hand delivered to the mayor and city council of a city, or board of selectmen of a town, and in the case of either a city or a town, to its board of assessors, to its planning board and conservation commission, if any, and to the state forester.

A notarized affidavit that the landowner has mailed or delivered a notice of intent to sell or convert shall be conclusive evidence that the landowner has mailed the notice in the manner and at the time specified. Each affidavit shall have attached to it a copy of the notice of intent to which it relates.

The notice of intent to sell or convert shall be considered to have been duly mailed if addressed to the mayor and city council or board of selectmen in care of the city or town clerk; to the planning board and conservation commission if addressed to them directly; to the state forester if addressed to the commissioner of the department of conservation and recreation and to the assessors if addressed to them directly.

If the notice of intent to sell or convert does not contain all of the material as described above, then the town or city, within 30 days after receipt, shall notify the landowner in writing that notice is insufficient and does not comply.

For a period of 120 days after the day following the latest date of deposit in the United States mail of any notice which complies with this section, the city or town shall have, in the case of intended sale, a first refusal option to meet a bona fide offer to purchase the land.

In the case of intended or determined conversion not involving sale, the municipality shall have an option to purchase the land at full and fair market value to be determined by an impartial appraisal performed by a certified appraiser hired at the expense of the municipality or its assignee, the original appraisal to be completed and delivered to the landowner within 30 days after the notice of conversion to the municipality. In the event that the landowner is dissatisfied with the original appraisal, the landowner may, at the landowner's expense contract for a second appraisal, to be completed within 60 days after the delivery of the notice to convert. If, after completion of the second appraisal, the parties cannot agree on a consideration, the parties will contract with a mutually acceptable appraiser for a third appraisal whose cost will be borne equally by both parties. The third appraisal shall be delivered to both parties within 90 days after the notice of conversion to the municipality and shall be the final determination of consideration. Upon agreement of a consideration, the city or town shall then have 120 days to exercise its option. During the appraisal process, the landowner may revoke the intent to convert at any time and with no recourse to either party.

The option may be exercised only after a public hearing followed by written notice signed by the mayor or board of selectmen, mailed to the landowner by certified mail at the address that is specified in the notice of intent. Notice of the public hearing shall be given in accordance with section 23B of chapter 39.

The notice of exercise shall also be recorded at the registry of deeds and shall contain the name of the record owner of the land and description of the premises adequate for identification of them.

The notice to the landowner of the city or town's election to exercise its option shall be accompanied by a proposed purchase and sale contract or other agreement between the city or town and the landowner which, if executed, shall be fulfilled within a period of not more than 90 days after the date the contract or agreement, endorsed by the landowner, is returned by certified mail to the mayor or board of selectmen, or upon expiration of any extended period that the landowner has agreed to in writing, whichever is later.

At the public hearing or a further public hearing, the city or town may assign its option to a nonprofit conservation organization or to the commonwealth or any of its political subdivisions under the terms and conditions that the mayor or board of selectmen may consider appropriate. Notice of the public hearing shall be given in accordance with section 23B of chapter 39.

The assignment shall be for the purpose of maintaining no less than 70 per cent of the land in use as forest land as defined in section 1 of this chapter, as agricultural and horticultural land as defined in sections 1 and 2 of chapter 61A or as recreation land as defined in section 1 of chapter 61B, and in no case shall the assignee develop a greater proportion of the land than was proposed by the developer whose offer gave rise to the assignment. All land other than land that is to be developed shall then be bound by a permanent deed restriction that meets the requirements of chapter 184.

If the first refusal option has been assigned to a nonprofit conservation organization or to the commonwealth or any of its political subdivisions as provided in this section, the mayor or board of selectmen shall provide written notice of assignment to the landowner.

The notice of assignment shall state the name and address of the organization or agency of the commonwealth which will exercise the option in addition to the terms and conditions of the assignment. The notice of assignment shall be recorded with the registry of deeds.

Failure to record either the notice of exercise or the notice of assignment within the 120 day period shall be conclusive evidence that the city or town has not exercised its option.

If the option has been assigned to a nonprofit conservation organization or to the commonwealth or any of its political subdivisions, the option may be exercised by the assignee only by written notice to the landowner signed by the assignee, mailed to the landowner by certified mail at the address that is specified in the notice of intent.

The notice of exercise shall also be recorded with the registry of deeds and shall contain the name of the record owner of the land and description of the premises adequate for identification of them.

The notice of exercise to the landowner shall be accompanied by a proposed purchase and sale contract or other agreement between the assignee and landowner which, if executed, shall be fulfilled within a period of not more than 90 days, or upon expiration of any extended period that the landowner has agreed to in writing, from the date the contract or agreement, endorsed by the landowner, is returned by certified mail to the assignee.

During the 120 day period, the city or town or its assignees, shall have the right, at reasonable times and upon reasonable notice, to enter upon the land for the purpose of surveying and inspecting said land, including but not limited to soil testing for purposes of Title V and the taking of water samples.

The city or town or its assignee shall have all rights assigned to the buyer in the purchase and sales agreement contained in the notice of intent.

If the city or town elects not to exercise the option, and not to assign its right to exercise the option, the city or town shall send written notice of nonexercise signed by the mayor or board of selectmen to the landowner by certified mail at the address that is specified in the notice of intent. The notice of nonexercise shall contain the name of the owner of record of the land and description of the premises adequate for identification of them, and shall be recorded with the registry of deeds.

No sale or conversion of the land shall be consummated until the option period has expired or the notice of nonexercise has been recorded with the registry of deeds, and no sale of the land shall be consummated if the terms of the sale differ in any material way from the terms of the purchase and sale agreement which accompanied the bona fide offer to purchase as described in the notice of intent to sell except as provided herein.

This section shall not apply to a mortgage foreclosure sale, but the holder of a mortgage shall, at least 90 days before a foreclosure sale, send written notice of the time and place of the sale to the parties in the manner described in this section for notice of intent to sell or convert, and the giving of that notice may be established by an affidavit as described in this section.

Section 10. All buildings located on land which is valued, assessed and taxed on the basis of its forest ecosystem use in accordance with the provisions of this chapter and all land occupied by a dwelling or regularly used for family living shall be valued, assessed and taxed by the same standards, methods and procedures as other taxable property.

Section 11. Continuance of land valuation, assessment and taxation under the provisions of this chapter shall depend upon continuance of such land in forest ecosystem use and compliance with other requirements of this chapter and not upon continuance in the same owner of title to such land. Liability to roll-back taxes, determined pursuant to section 8 shall attach when such land no longer qualifies as forest ecosystem land actively and shall be the obligation of the then owner of the land. For purposes relating to roll-back taxes such qualification shall depend on the actual use of such land for the previous 5 years, and not on the filing of application under section 3 for any year.

Section 12. If, by conveyance or other action of the owner thereof, a portion of land which is valued, assessed and taxed under the provisions of this chapter is separated for a use which does not qualify as forest ecosystem land, the land so separated shall be subject to liability for conveyance or roll-back taxes applicable thereto, but such separation shall not impair the right of the remainder of such land to continuance of valuation, assessment and taxation thereunder; provided, however, that such remaining land continues to so qualify.

Section 13. Land qualifying for valuation, assessment and taxation under this chapter shall be subject to special assessments or betterment assessments to such pro rata extent as the service or facility financed by such assessment is used for improving the forest ecosystem use capability of said land or for the personal benefit of the owner thereof. This assessment shall, however, upon application, be suspended during the time the land is in classified forest ecosystem use and shall become due and payable as of the date when the use of the land is changed. Payment of the assessment and interest on it shall be made in accordance with section 13 of chapter 80, but the interest shall be computed from the date of the change in use. If only a portion of a tract of land which benefits from a suspension of payment is changed from that use, the assessment shall become due and payable as of the date when the use was changed only to the extent of and in the proportion that the frontage of that portion bears to the street frontage of the entire tract of land which originally benefited from a suspension of payment. Upon receipt of full payment of a portion of a suspended assessment, the tax collector shall dissolve the lien for the assessment insofar as it affects the portion of the land changed from forest ecosystem use. The lien for the portion of the original assessment which remains unpaid shall continue and remain in full force and effect until dissolved in accordance with law. A request for this release shall be made in writing to the tax collector and shall be accompanied by a plan and other information that is required in the case of a request for a division of an assessment under section 10.

Section 14. The assessment, collection, apportionment and payment over of the roll-back taxes imposed by section 8 shall be governed by the procedures provided for the assessment and taxation of omitted property under section 75 of chapter 59. Such procedures shall apply to each tax year for which roll-back taxes may be imposed notwithstanding the limitation set forth in said chapter 59 with respect to the periods for which omitted property assessments may be imposed. Any person aggrieved by any determination or assessment by the board of assessors under this chapter may within 30 days of the date of notice thereof apply in writing to the assessors for modification or abatement thereof. Any person aggrieved by the refusal of the assessors to modify such a determination or make such an abatement or by their failure to act upon such an application may appeal to the appellate tax board within 30 days after the date of notice of their decision or within 3 months of the date of the application, whichever date is later. It shall be a condition of such appeal with respect to the annual general property tax that the asserted tax be paid, but no payment shall be required as a condition of such appeal with respect to any asserted conveyance tax or roll-back tax. If any payment of any tax imposed by this chapter should be made and as the result of any such modification or abatement by the board of assessors or decision by the appellate tax board it shall appear that any such tax has been overpaid, such excess payment shall be reimbursed by the town treasurer with interest at the rate of 6 per cent per annum from time of payment. Collection of any conveyance or roll-back taxes, by sale or taking or otherwise, may be stayed by the appellate tax board while any such appeal is pending. Any partial payment of the asserted tax that may be required by the appellate tax board in connection with such tax shall not exceed one-half of the asserted tax.

Section 15. In connection with any proposed or completed sale or other transfer of any land which has been valued, assessed and taxed under the provisions of this chapter, the owner of record of the land may apply to the board of assessors for a certificate of the amount of conveyance tax and roll-back tax, if any, payable by reason of such sale or other transfer, or that no such tax is payable and stating the amount of any conveyance or roll-back taxes that are payable with respect to such land. Such certificate shall be provided to the applicant within 20 days after application therefor. Such certificate may be recorded with the registry of deeds, and upon such recording of such a certificate become payable, or a certificate by the collector of taxes that the amount of tax stated in such certificate of the board of assessors has been paid, all liens on such land for taxes under this chapter shall terminate, except that any liens for any roll-back taxes assessed by reason of land ceasing to qualify for valuation, assessment and taxation under this chapter after the date of such sale or other transfer, shall continue. In connection with the issuance of such a certificate, the board of assessors may rely upon their own records, affidavits and such other information as they may deem appropriate. The board of assessors shall charge $6 for each certificate so issued, and the money so received shall be paid into the town treasury.

Section 16. In determining the equalization required by section 9 of chapter 58, the commissioner of revenue shall determine the value of such land on the basis of its forest ecosystem use.

Section 17. The factual details to be shown on the tax list of a board of assessors with respect to land which is valued, assessed and taxed under this chapter shall be the same as those set forth by said board with respect to other taxable property in the same city or town.

Section 18. The commissioner of revenue shall promulgate such rules and regulations and shall prescribe the use of such forms and procedures as he deems appropriate to and consistent with effectuation of the purposes of this chapter.
