What documentation do you need for permitting an industrial operation from an environmental perspective?

Why it is appropriate to address the environment already in the project

For industrial operations, environmental documentation is often addressed only when requested by the building authority, regional authority, Regional Public Health Authority, Czech Environmental Inspectorate or the authority issuing the unified environmental opinion. That is too late. At that stage the technology is usually designed, exhausts placed, traffic routes chosen and the layout of the hall almost final.

If environmental requirements are addressed only afterwards, it may turn out that the exhaust is too low, the technology is too close to residential development, there is no measurement point on the duct, waste handling is not resolved, or noise from HVAC units exceeds what the project can realistically achieve.

For industrial operations, the greatest time saving is often achieved when air quality, noise, water and waste are assessed before the final technical design.

This typically applies to paint shops, welding shops, boiler plants, backup sources, wood-processing operations, recycling sites, food-processing operations, chemical storage warehouses, automotive production, waste facilities or technologies with significant ventilation.

Basic overview of documentation

The specific scope of documentation depends on the technology, capacity, location of the project and requirements of the authorities. For a simple operation a basic technical description and several statements may suffice. For a larger industrial project a whole set of studies, reports and operational documents may be needed.

This table is indicative. The actual scope is always determined according to the specific project, not according to the general name of the operation.

Air quality: sources, exhausts and emission documentation

For air quality the first step is to determine whether the technology contains stationary sources of air pollution and whether these are sources listed in Annex 2 to the Air Protection Act. What is decisive is usually the type of technology, designed capacity, rated thermal input, consumption of organic solvents, quantity of material processed, or character of waste gases.

Typical industrial sources include for example boiler plants, combustion engines, paint shops, welding shops, wood-processing operations, crushing and sorting lines, foundries, surface treatment, composting plants, landfills or technologies with dust and VOC extraction.

For air quality the following are usually addressed:

Practically important: an exhaust should not in the project be just "somewhere on the roof". Its height, direction, flow rate, connection to the specific technology, access for measurement and relationship to surrounding development need to be addressed.

Dispersion study

A dispersion study evaluates how emissions from a source manifest themselves in surrounding air. It is used for example for combustion sources, paint shops, recycling lines, crushers, landfills, composting plants, backup sources, dusty operations or projects with significant traffic.

A dispersion study is not just a formal calculation. To be usable it must be based on realistic input data: operating hours, emission parameters, exhaust height, flow rates, flue gas temperature, dust from handling, traffic intensity and local conditions.

Typical mistake: the project assumes an exhaust low on the façade or in an enclosed courtyard and the dispersion study is addressed only after completion of the design. At that point technical modification of the exhaust may be complicated.

Expert report

An expert report under the Air Protection Act is for some listed sources an important input for the operating permit. It assesses the technology, classification of the source, pollutants, emission limits, proposed measures, method of determining emissions, and compliance with statutory requirements.

An expert report is often addressed for example for new boiler plants, paint shops, facilities with organic solvents, recycling lines, combustion sources, technological exhausts, or when changing an existing source.

For the designer it is important that an expert report may reveal technical requirements that should be incorporated into the design: measurement ports, access platforms, separators, filters, stack height, operating regime or record-keeping requirements.

Noise: technology, HVAC and traffic

A noise study for industrial operations is addressed especially when residential development, protected outdoor areas of buildings, schools, healthcare facilities or recreational areas are nearby. It is not only noisy machines inside the hall. Outdoor sources often decide the outcome: fans, compressors, cooling units, HVAC exhausts, loading, handling equipment and heavy goods traffic.

For noise it is important to distinguish two levels. The first is noise in the work environment — exposure of employees. The second is noise spreading into the surroundings, which assesses the impact of the operation on protected areas outside the site.

For a new operation it is appropriate to address noise in advance. Retrofit soundproofing of technology, exhausts or façades is usually more expensive than correct placement of sources in the design.

Waste and facility operating rule

For an industrial operation it is necessary to describe what wastes will arise, where they will be collected, how they will be handed over to an authorised person, and whether the operation will itself be a waste handling facility.

A different regime applies to an ordinary waste producer in production and a different one to a facility for collection, storage, treatment, recovery or disposal of waste. For waste handling facilities a regional authority permit and facility operating rule are typically addressed.

For waste, the project usually addresses:

• types of waste arising,
• hazardous waste and its secure collection,
• storage capacity,
• impermeable surfaces and emergency containment,
• packaging from chemical substances,
• sludges, filter materials, sorbents and residues of raw materials,
• operating rule if it is a waste facility.

For waste facilities it is important to distinguish annual capacity and instantaneous capacity. Annual capacity states how much waste passes through the facility per year. Instantaneous capacity determines how much waste may be on the site at one time. This figure is important for the operating rule, fire safety, water, odour and EIA.

Water: rainwater, process water and emergency water

Water management is often underestimated at industrial operations. Yet water often decides whether the site is technically and permitting-wise well prepared. Rainwater from roofs and paved areas, process water, sanitary wastewater, wash water, emergency containment of hazardous substances, and possibly discharge to sewer or a watercourse are addressed.

For operations with chemical substances, oils, waste, handling of raw materials or outdoor areas it is important to design what happens in case of substance release, fire intervention or heavy rainfall. It is not enough merely to mark sewer inlets on drawings.

The water part is often reflected in the unified environmental opinion and in requirements of affected authorities. For more complex operations it is appropriate to address it together with the plumbing designer, fire safety specialist and environmental specialist.

EIA and screening procedure

EIA is addressed for projects listed in Annex 1 to the Environmental Impact Assessment Act. For category I projects assessment is always mandatory; for category II projects a screening procedure is usually conducted in which the relevant authority decides whether the project will be further assessed.

For industrial operations EIA may concern for example waste facilities, energy, chemical production, surface treatment, food-processing operations, warehouses, recycling sites, changes to existing operations or significant capacity increase.

From the investor's perspective it is important that EIA is not just "extra paperwork". It can affect project schedule, scope of studies, communication with the public, operating conditions and subsequent proceedings. If the risk of EIA is real, it should be evaluated at the outset.

Unified environmental opinion

The unified environmental opinion is today a key input for permitting a project under the Building Act. The purpose of the unified environmental opinion is to concentrate selected environmental requirements into one opinion instead of a series of separate steps.

For the investor and designer this does not mean that a simple application is enough. On the contrary: the application for a unified environmental opinion must contain documentation needed for the individual environmental areas that relate to the project.

For the unified environmental opinion it is therefore important to have consistent documentation:

• the same description of technology in the project, studies and application,
• the same capacities in all documents,
• the same exhausts, stacks and operating hours,
• the same traffic intensities,
• clear solution for water and waste,
• documented measures against noise, dust and emissions.

Practically important: the unified environmental opinion does not replace quality preparation of documentation. It only process-wise concentrates environmental opinions into one output.

Operating rules

An operating rule is needed where a specific legal regime or permit requires it. In industrial practice the operating rule for a source of air pollution, operating rule for a waste facility, and where relevant emergency or operational documents for water and hazardous substances are most often addressed.

A good operating rule should not be formal text. It should describe actual operation, verifiable parameters, maintenance, records, fault conditions and specific measures.

The operating rule must correspond to the project and actual operation. If the technology changes but the operating rule remains old, problems arise during inspection and when changing the permit.

What data the investor should provide at the outset

It is best to start with a brief technical description of the project. It need not be perfect, but it must allow determination of which environmental areas will be addressed. For initial assessment basic documentation and several key data are usually sufficient.

The earlier these data are available, the more precisely it can be determined whether a noise study, dispersion study, expert report, EIA notification, operating rule or other documentation will be needed.

Most common mistakes by investors and designers

The most common mistake is to treat the environmental part as a final appendix to the project. For industrial operations it is part of technology design. Exhaust height, fan location, traffic route or placement of noisy technology can decide whether the project can be permitted without complex additional measures.

Another frequent problem is inconsistency between documentation. The project states a different capacity than the EIA notification, the dispersion study assumes different exhausts than the HVAC drawing, the noise study works with a different number of vehicles than the traffic part, and the operating rule describes a different regime than the technical report.

For industrial operations the following must be consistent in particular:

• capacities,
• operating hours,
• exhausts,
• traffic intensities,
• technology,
• waste,
• water management,
• protective measures.

It is often consistency of documentation that decides whether the authority requests only minor supplementation or whether the process begins to become complicated.

Recommended procedure

For a new industrial operation or significant change it is appropriate first to carry out environmental screening. This verifies whether the project falls under EIA, whether a unified environmental opinion will be needed, whether it contains listed air pollution sources, whether waste permitting is required, whether noise may be a problem, and what documentation needs to be prepared for building permission or subsequent proceedings.

Specific studies and documents are then added. For larger projects it is appropriate for the designer, investor and environmental specialist to agree already before the final technology design. This prevents a situation where exhausts, noise silencers, waste storage or drainage of areas must be changed afterwards.

Summary

Permitting an industrial operation from an environmental perspective usually requires a combination of several inputs. Air quality, noise, waste, water, EIA, unified environmental opinion, operating rules, expert reports and dispersion studies are most often addressed. The scope of documentation depends on technology, capacity, location, operating regime and requirements of affected authorities.

For investors and designers it is key to address environmental documentation in good time and consistently. The same data must appear in the project, application for unified environmental opinion, studies, reports and operational documents. The greatest problems usually do not arise from the technology itself, but from unclear capacities, poorly placed exhausts, underestimated noise, unaddressed water, or inconsistency between documents.

Send us a basic description of the technology, capacities, site drawing, data on exhausts, HVAC, traffic, waste, water and any requirement from an authority. We will propose what environmental documentation will be needed for permitting the industrial operation and in what order it is appropriate to prepare it.

The article is based in particular on the following legislation and methodological sources:

• Act No. 148/2023 Coll., on the unified environmental opinion,
• MoE methodological guideline on introduction of the unified environmental opinion,
• Act No. 100/2001 Coll., on environmental impact assessment,

• Government Regulation No. 272/2011 Coll., on protection of health from adverse effects of noise and vibration.

The MoE methodological guideline describes the unified environmental opinion as a tool for procedural integration of selected environmental steps and states that the unified environmental opinion is issued for projects permitted under the Building Act and for projects in the EIA regime. Act No. 100/2001 Coll. sets the EIA regime and screening procedure. Act No. 201/2012 Coll. distinguishes listed and non-listed stationary sources in Annex 2. Act No. 541/2020 Coll. and Decree No. 273/2021 Coll. regulate operation of waste handling facilities and requirements for operating rules. Government Regulation No. 272/2011 Coll. is the basic regulation for evaluation of noise in protected areas and at workplaces.
