In short
The Incidental Operational Single Permit is a project’s environmental umbrella. It includes one or more of four permits: the Incidental Activity to an Authorised Work, the Incidental Activity to a Public Infrastructure Work, the Authorisation for Cutting, Pruning, Transplanting and Planting Trees, and the Consolidated General Permit. All activities applicable to the project must be selected in a single application. The earth-movement trigger is concrete: every extraction, excavation, removal and dredging of the earth’s crust components incidental to authorised works exceeding forty cubic metres and not qualifying for an exemption. The tree trigger is wider still: every construction or land-development project or activity, public or private, proposing to cut, fell, debark, move or in any other way affect one or more trees. And inside the Consolidated General Permit travel three permits that used to go separately: Erosion Control and Sedimentation Prevention, with its CES Plan signed and sealed by an engineer or architect, applying from nine hundred square metres of surface; Operating an Emission Source; and Non-Hazardous Solid Waste Generating Activity. The permit lasts five years, may be amended at any time through the SUI, and to renew it you must file not less than ninety days before it expires.
What is it?
It is Chapter 3.4 of Joint Regulation No. 9473, titled Environmental Permits, adopted under and in harmony with Act 161-2009 and Act 416-2004 to establish the processes for evaluating the Incidental Operational Single Permit. The permit groups into a single application the environmental authorisations that used to be sought separately, and once issued, OGPe’s system generates a simultaneous notice to the DRNA for oversight of the Consolidated General Activity and to the DRNA for oversight of the Authorisation for Cutting, Pruning, Transplanting and Planting Trees. This guide covers what the permit is, when it is needed, what is filed and how it is kept in force. The number of trees that must be planted, the planting standards and the alternative mitigation routes have their own guides on this site, written from the same reading.
Who can do it?
You need the permit, among other cases, if your project moves more than forty cubic metres of earth-crust components incidental to an authorised work and does not qualify for an exemption; if that same activity is incidental to a public infrastructure work promoted by the ACT, DTOP, AAA, AEE, AFI, other infrastructure agencies or the municipalities; if your construction or land-development project, public or private, proposes to cut, fell, debark, move or in any other way affect one or more trees; or if your work falls under the Consolidated General Activity, which requires the Erosion Control and Sedimentation Prevention Permit for constructions or demolitions without asbestos or lead paint on areas of nine hundred square metres or more where the earth-crust volume exceeds forty cubic metres. The chapter has four express exclusions, and the one most people use is the small tree: it does not apply where the tree’s trunk diameter is under four inches and only a pruning is done that removes not more than a third of the crown’s total foliage.

Step by step
Step 1: Which permits go inside the PUI
The Incidental Operational Single Permit includes one or more of these permits for construction and demolition works: the Incidental Activity to an Authorised Work Permit, the Incidental Activity to a Public Infrastructure Work Permit, the Authorisation for Cutting, Pruning, Transplanting and Planting Trees, and the Consolidated General Permit. The operative rule is in the same section: all activities applicable to your project must be selected in a single application. They are not four filings, they are one with four boxes. And once issued, OGPe’s system generates a simultaneous notice to the DRNA for oversight of the Consolidated General Activity and to the DRNA for oversight of the Authorisation for Cutting, Pruning, Transplanting and Planting Trees.
Step 2: The forty cubic metres
Every extraction, excavation, removal and dredging of the earth’s crust components incidental to authorised works exceeding forty cubic metres, meeting one or more of the regulation’s criteria and not qualifying for an exemption, requires an Incidental Operational Single Permit including the Incidental Activity to an Authorised Work. The criteria are two: that the activity take place on private land, on private watercourse beds on private land or on the State’s patrimonial land; and that, if the activity produces surplus material, that material go to another duly approved project, an authorised solid-waste disposal system, a private property holding a fill-deposit permit, or a public purpose. The same forty-cubic-metre rule applies to public infrastructure works promoted by the ACT, DTOP, AAA, AEE and AFI, other infrastructure agencies and the municipalities — even where that activity is exempt from filing a construction permit with OGPe.
Step 3: A single tree already brings you into the permit
The tree rule is the chapter’s widest: every construction or land-development project or activity, public or private, proposing to cut, fell, debark, move or in any other way affect one or more trees, including infrastructure works promoted by a government instrumentality exempt from filing a construction permit. One or more. There is no quantity threshold. In addition, the work’s owner must guarantee one hundred per cent success for all plantings required by the regulation or by any agreement with the DRNA, and alternatives must be presented for managing and disposing of the vegetative material generated by cutting and pruning, under Chapter IX of the Recycling Regulation.
Step 4: The four exclusions
The chapter’s provisions do not apply in four cases. First, to construction, operation and maintenance activities of projects the DRNA develops, or of the agencies or private firms to which the DRNA has entrusted the construction, operation or maintenance of its projects. Second — and this is the one most people use — where the tree’s trunk diameter, the DAP, is under four inches and only a pruning is done that removes not more than a third of the crown’s total foliage. Third, to cutting, pruning and branch-removal by agencies empowered by law to do it, such as the AEE. And fourth, to cutting, pruning, branch-removal, planting and mitigation done under agreements formalised with the DRNA.
Step 5: The Consolidated General Activity and its nine hundred metres
Three individual permits are consolidated inside the Incidental Operational Single Permit as a Consolidated General Activity. The Erosion Control and Sedimentation Prevention Permit, the CES, is required for every construction or demolition of structures not containing asbestos or lead paint, on land surface areas of nine hundred square metres or more, where the total volume of earth-crust components to be used as fill or extracted, stored, disposed of, cleared, piled or removed exceeds forty cubic metres. The Permit to Operate an Emission Source applies to works requiring one for earth movement and construction phases in areas of nine hundred square metres or more. And the Non-Hazardous Solid Waste Generating Activity Permit covers the non-habitual generation of non-hazardous solid waste as the DRNA defines it. The DRNA’s Regulation for Processing General Permits must also be complied with.
Step 6: The CES Plan: who signs it and what it carries
The Erosion and Sedimentation Control Plan is a written document, signed and sealed by the engineer or architect who prepared it, with each of its sections labelled. It carries an explanatory memorial; evidence of the licences of the professionals certifying it; location and graphic representation of the affected and abutting areas; a plan of current and proposed levels; a drainage plan with the location of existing systems, runoff calculations, perennial or intermittent water bodies and natural systems such as wetlands and sinkholes; a storm plan with the final drainage system and its discharge points; the CES Plan drawing with the erosion control and sedimentation prevention measures to be implemented; the description of those provisional and permanent measures with design, specifications and maintenance schedule; identification of the storage location; the implementation and maintenance cost estimate; the document with the forestation or stabilisation activities; and three certifications signed and sealed in original: that of the engineer or architect who prepared the plan, that of any other professional who prepared included documents, and that of the Inspector in charge of implementation. It closes with the certification that the off-site disposal place holds a current permit to receive earth-crust material and a copy of the construction permit.
Step 7: If there is demolition: asbestos and lead
The Solid Waste Operation Plan includes the activity’s area and duration, the type and quantity of waste anticipated, the procedures, equipment and staff for collection and storage, the final disposal procedures and place, a copy of the Permit to Operate Non-Hazardous Solid Waste Collection or Transportation Services, a letter from the company providing the service with the final disposal facility’s information, and a copy of the final disposal manifest signed in original by the owner, authorised representative or operator. And if the activity includes demolition, two certifications must be included: one stating the structure to be demolished is free of asbestos material, signed and sealed by the licensed professional who prepared it; and another stating it is free of lead paint, signed by the inspector or risk assessor certified by the DRNA.
Step 8: The Forestation Plan and the IA de Siembra
For the tree cutting, pruning, transplanting and planting activity, a Forestation or Compensation Plan prepared and signed by an OGPe-authorised IA de Siembra is filed. That plan carries the reasons for the cutting, pruning or removal and a description of the affected area’s environmental conditions; a forest inventory in table form, prepared, signed and sealed by the IA de Siembra, listing every tree with a DAP of four inches or ten centimetres or more with its scientific name, common name, DAP, height and condition, plus the rare, threatened, critical or endangered species; the proposed action for each tree; the tree inventory overlaid on the survey plan, with the trees numbered and those to be cut and preserved marked, signed and sealed by the IA de Siembra; the forestation plan overlaid on the same survey plan; and the specifications, measures and schedule for maintaining the planting. There are also two certifications the IA de Siembra must upload to the SUI case: one at fifty per cent of the project and another at one hundred per cent, stating they inspected the work and it complies. And on transplants, the regulation warns: if the transplanted tree does not survive, it is mitigated under Rule 3.4.2.
Step 9: The trees not touched without a permit
No person or agency, by themselves or through their IA de Siembra, may cut, fell, debark or in any other way affect these trees, on public or private property, without first obtaining an Incidental Operational Single Permit: those whose characteristics are indispensable or necessary for forest use, including watershed protection, erosion control and the environment’s ecological balance; species protected by state or federal law and classified as rare, scarce, threatened, vulnerable or endangered; those located in public squares and parks; those indispensable to an essential public utility purpose; and those conglomerated on public land that share an ecosystem, sit within the same watershed and function to protect waters, prevent sedimentation of water bodies and control erosion.
Step 10: Five years, and ninety days to renew
The Incidental Operational Single Permit has a validity of five years. It may be amended at any time by filing an application through the SUI, and the amendment must include any change in plans, documents and certifications. To renew it, the application must be filed through the SUI not less than ninety days before the expiry date, accompanied by a sworn declaration that the conditions stated in the permit being renewed have not changed — such as title, rustic character, area and encumbrances — and that the environmental document originally filed has not changed either; by the sign notice under Rule 2.1.19 of Volume II; and, if the proponent is a corporation, by a current Certificate of Good Standing issued by the Department of State.
Step 11: If you sell the property
Where an entity changes name or a property changes owner, OGPe transfers the permit immediately to the new owner or entity, provided a declaration from the previous owner accepting the transfer or a document evidencing title is submitted. The new owner or operator is subject to the same limitations, conditions and requirements of the permit as originally issued. And a warning for the buyer: the permit’s new owner is responsible for any violation of the Incidental Operational Single Permit’s conditions from the moment it was transferred into their name.
Where to do it
The application is filed with OGPe, complying with the general requirements of Rule 2.1.9 of Volume II and with each activity’s specific requirements. Amendments and renewal are filed through the SUI. The OGPe-authorised IA de Siembra uploads to the SUI case the two Forestation Plan certifications, at fifty and one hundred per cent of the project. Once the permit is issued, OGPe’s system generates a simultaneous notice to the DRNA for oversight of the Consolidated General Activity and of the Authorisation for Cutting, Pruning, Transplanting and Planting Trees.
How long it takes
What to do if something goes wrong
The starting mistake is not ticking all the boxes: the regulation says all activities applicable to your project must be selected in a single application, and discovering mid-project that the tree one was missing forces an amendment. The three numbers that decide whether it applies to you are forty cubic metres of earth movement, nine hundred square metres of surface for the CES and the emission source, and a single tree for the cutting authorisation. If your case is a small pruning, look at the exclusion: it does not apply where the tree has a DAP under four inches and only a pruning removing a third or less of the crown’s foliage is done. If you are demolishing, get the two certifications early — free of asbestos, signed and sealed by the licensed professional, and free of lead paint, signed by the inspector or risk assessor certified by the DRNA — because without them the Operation Plan is not complete. If your permit is nearing expiry, count ninety days back from the expiry date: that is the last day to file the renewal. And if you buy a property with a current permit, bear in mind you will be responsible for any violation from the moment it is transferred into your name. Five caveats. First: we publish no cost or processing time; the chapter fixes no fee for the permit and estimates no duration, and the periods we quote are terms in the text. Second: we did not read Act 161-2009, Act 416-2004 or its Article 4(B)(3), Regulation 6825 of 2004, Regulation 4209 of 1990, Rules 2.1.9 and 2.1.19 of Volume II, Rule 3.5.13 on explosives, or the DRNA’s Regulation for Processing General Permits; we name them because the chapter sends readers to them. Third: we read the whole chapter, but this guide covers Rule 3.4.1 and Sections 3.4.4.10 to 3.4.4.14; the number of trees to plant, the planting standards and the alternative mitigation routes have their own guides on this site. Fourth: the permit to cut trees under the Forests Act, with its fines, is a different thing and has its own guide; this is the Joint Regulation route for construction works. Fifth, on source defects: Section 3.4.1.1’s list jumps from the numbered permits to an unlettered sentence and then to paragraph (c), so what would be paragraph (b) has lost its letter; Section 3.4.1.2(c) mixes numbering, with its sub-paragraphs and the exclusions running on without their own number; and Section 3.4.1.2(d) restarts its list at "a." inside a paragraph that is already (d). We reproduce all of it as printed. And a note on the link: the file the Board publishes is named "Reglamento Conjunto de Emergencia", but the document inside is Joint Regulation No. 9473 of 16 June 2023.
Common mistakes
- Filing only one of the activities when the project needs several: the regulation asks for all of them in a single application.
- Believing that moving less than forty cubic metres of earth always exempts you: you must also check the CES and the emission source for the nine hundred square metres.
- Assuming cutting a single tree needs no permit in a construction work.
- Applying the small-tree exclusion to a cutting: the exclusion is only for pruning a tree with a DAP under four inches and a third or less of the foliage.
- Commissioning the Forestation Plan from someone who is not an OGPe-authorised IA de Siembra.
- Forgetting the IA de Siembra’s two certifications, at fifty and one hundred per cent of the project.
- Demolishing without the asbestos-free and lead-paint-free certifications.
- Filing the renewal with less than ninety days before the permit expires.
Frequently asked questions
What does the Incidental Operational Single Permit include?
It includes one or more of these permits for construction and demolition works: the Incidental Activity to an Authorised Work Permit, the Incidental Activity to a Public Infrastructure Work Permit, the Authorisation for Cutting, Pruning, Transplanting and Planting Trees, and the Consolidated General Permit. All activities applicable to your project must be selected in a single application.
From how much earth movement is it needed?
Every extraction, excavation, removal and dredging of the earth’s crust components incidental to authorised works exceeding forty cubic metres, meeting one or more of the regulation’s criteria and not qualifying for an exemption, requires the permit. The same forty-cubic-metre figure appears in the Erosion Control Permit, which additionally requires areas of nine hundred square metres or more.
Do I need a permit to cut a single tree?
In a construction or land-development work, yes. The regulation covers every construction or land-development project or activity, public or private, proposing to cut, fell, debark, move or in any other way affect one or more trees. The nearest exclusion is the minor pruning: where the tree has a DAP under four inches and only a pruning removing not more than a third of the crown’s total foliage is done.
What is the CES Plan and who signs it?
It is the Erosion and Sedimentation Control Plan: a written document, signed and sealed by the engineer or architect who prepared it, with labelled sections including a memorial, licences, level, drainage, storm and CES plans, the description of provisional and permanent measures, the cost estimate, the forestation or stabilisation document and three certifications signed and sealed in original, among them that of the Inspector in charge of implementation.
How long does the permit last and how do I renew it?
The Incidental Operational Single Permit has a validity of five years. Every renewal application must be filed through the SUI not less than ninety days before the expiry date, accompanied by a sworn declaration that neither the conditions nor the original environmental document have changed, the sign notice, and a current Certificate of Good Standing if the proponent is a corporation.
What happens if I sell the property with the permit in force?
Where an entity changes name or a property changes owner, OGPe transfers the permit immediately to the new owner, provided a declaration from the previous owner accepting the transfer or a document evidencing title is submitted. The new owner is subject to the same limitations and conditions, and is responsible for any violation from the moment the permit was transferred into their name.
