WHAT DOES INTEGRATED PERMITTING MEAN?(presentation based on H1 method, UK, Thames Region)


Integration of permitting work in Danish counties

  • Example : Ribe County:

    • 9 employees making permits (approximately 200.000 inhabitants in the county)

    • Each Employee has 3 tasks:

      • Making permits within his/hers specific branch knowledge

      • Responsible for a specific sector plan or yearly task, including maintenance of the legislation

      • Maintain technical expertise within 1 specific area

    • For each permit there is a primary case officer and a secondary case officer. The secondary case officer shall make quality control of the permit using a questionnaire and give day to day sparring to the primary case officer

    • The case officer can use informal assistance from the relevant technical experts.


Specialist areas:

Structure of Assessment

Scope & options

Emissions inventory

assess environmental impacts

Compare impacts between options

assess costs

select best option


Scope and Options - 1

  • Explain why you are doing the assessment:

  • either

  • To conduct a cost/benefit appraisal of options to determine BAT for selected releases from an installation because:

    • deviating from indicative BAT in BREF

    • several candidates for BAT

    • no indicative BAT in BREF

  • or

  • To carry out environmental assessment of emissions resulting from the installation as a whole


Methane emissions from a landfill site

Sulphur emissions from a coal-fired power station

Emissions from a pulp mill

Emissions from effluent treatment plant of a chemicals manufacturing facility

Scope and Options - 2

  • Describe scope of activities to be included


  • Types of techniques:

  • Raw materials

  • Abatement

  • process control

  • operating mode

  • design

Scope and Options - 3

  • Identify key environmental issues (and eliminate irrelevant ones) and receptors

  • Identify candidate options for BAT, by considering all relevant techniques to prevent and minimise pollution from all activities


Emissions Inventory - 1

  • Including:

  • Point source emissions to air

  • Point source emissions to surface water, groundwater and sewer

  • Waste emissions

  • Fugitive emissions to all media

  • Abnormal emissions from emergency relief vents, flares etc

  • Raw material consumption including energy and water


Emissions Inventory - 2

  • Describe:

  • Substances released

  • Source, including height, location, efflux velocity and total flow

  • Predicted normal and maximum emissions expressed on suitable basis Statistical basis

  • Predicted frequencies (if intermittent)

  • Plant loads at which data are applicable

  • Check all options meet any statutory emission limit values as laid down in EU Directives


Quantify the impacts

  • considerations

  • releases to air

  • releases to water

  • deposition to land

  • ozone creation

  • global warming

  • waste disposal

  • noise

  • odour

  • accidents

  • visual impact

  • method depends on type of impact:

  • local impacts: relate to level in environment

    -usually a maximum “protective” level

  • non-local impacts: relate to relative burden

    -no maximum “protective” level


local impacts - 1

  • estimate levels in environment after dispersion :- “Process Contributions” (PC)

  • compare PC against environmental benchmarks; EQSs

  • the benchmarks are based generally on a maximum “tolerable” concentration to a receptor in a medium

  • benchmarks for human and ecological protection are available and will be under constant revision


local Impacts - 2

  • Identify whether detailed modelling of emissions is needed , eg

    • if local receptors present which are sensitive to any of the significant emissions

    • if there is a risk of breaching an EQS

  • Add PC to background level to obtain total Predicted Environmental Concentration (PEC)

  • Check that PEC does not breach an EQS - these options will usually be unacceptable


local impacts - 3


local impacts - 4

  • normalise against benchmark:

    EQ = PC/ EQS

  • Summarise total impact by medium

    • EQ water

    • EQ air

    • EQ land


Non-local

  • Quantify Non-Local Impacts

  • Use relative Indices for

    • Global Warming

    • Ozone Creation

  • Waste:

    • quantify by category

    • describe disposal route

  • Summarise as total burden


Compare Options

  • If PCs from options are low compared to EQSs this has less influence on decision than when they are high

  • If existing environmental quality is poor then greater importance placed on this consideration in the assessment

  • Local proximity of sensitive receptors to certain environmental impacts may be important

  • Long term irreversible effects are less desirable than short term reversible effects

  • How big the contribution of the impact is in relation to national or EU targets

  • Bear in mind risk/accidents


Evaluate the Costs

  • Estimate the costs of implementing each of the options carried forward from the assessment, to allow a balanced judgement of the costs of controlling releases of substances against the environmental benefits

  • Not necessary if the operator proposes to implement the option which clearly represents the lowest environmental impact


Select BAT

  • balance environmental benefits against costs

  • justify priority impacts

  • show decisions clearly

  • use expert judgement


Case study: A Power plant

  • Step 1: Scope and options

  • “To decide the best technique to reduce sulphur emissions from a power plant”


Step 2: Candidate options and key environmental issues

Case study: A Power plant


Step 3: Emissions inventory

Case study: A Power plant


Case study: A Power plant

  • Step 4: Assess local impacts

  • Impossible to find locations for deposit of up to 30 mio. m3 solid waste (dry method over 30 years)

  • Gypsum (wet method) deposits has a risk for leaching of heavy metals to ground water, which is not acceptable.

  • Discharge of wastewater with heavy metals from the wet method is not in accordance with the hazardous substances directive (list I substances which should be eliminated).


Case study: A Power plant

  • Step 5: Assess regional and global impacts

  • Acidification:

  • Low – S Coal > End-of-pipe > N-gas (best option)

  • Eutrophication:

  • De-S, wet > low –S coal > De-S, dry > N-gas > SNOX (best option)

  • (assessed directly from emissions and discharges)


Case study: A Power plant

  • Step 6: Compare options

  • Due to unacceptable local impacts from heavy metals a deposit free solution is preferred and from assessment of regional and global impacts the following 2 methods is selected for further cost investigations:

  • N-gas

  • SNOX method


Case study: A Power plant

  • Step 7: Assess the cost

  • It is assessed that use of N-gas will raise the current power price with approx 7% compared to present price and cost 12 mio. EUR in installation of new burners etc.

  • The SNOX method is comparable in price to the other end-of-pipe solutions, but the method is not developed to a commercial level yet (only demo installations)


Case study: A Power plant

  • Step 8: Select BAT

  • BAT is the SNOX process when it is developed to a commercial level.

  • Until then N-gas firing is BAT
