Emission limit value

For mercury cellrooms it expects that the application of BAT will result in emission levels well below 2.0 g/te (of chlorine capacity) and notes that there are examples of plants achieving levels well below 1.0 g/te. Numerical emission limit values were set at 0.01 g/te for new plants (deliberately equivalent to a ban on mercury technology) but will not be decided for existing plant until two years after the Protocol enters into force (say, by 2004). 

The Directive is founded firmly in the concept of BAT (Best Available Techniques) -which is painstakingly defined in the text. Although the Directive does not set emission limit values per se, it does have procedures which set out the quantitative levels of emissions that can be expected to result from the application of BAT. The subtlety of this approach allowed all Member States to agree the Directive - but has led to considerable debate thereafter in terms of the balance of powers between the local competent authorities (who can, and usually do, set emission limits on a plant-by-plant basis) and the European Commission which is the guardian of BAT as set out under the Directive. 

One of the key elements of the WFD is the implementation of a combined approach of emission limit values and quality standards (for waters, sediments and biota), and also the phasing out of particularly hazardous substances. Accordingly, a list of 33 priority substances, which represent a significant risk to the aquatic environment at community level, was established. For the first time two surfactant metabolites, namely NP and OP, have been included in this priority list. 

The VOC Solvents Directive. Sets fugitive emission limit values for the Volatile Organic Compounds in the paint (EU, 1999b). 

In the foreseen revision of Directive 2004/26/EC stringent emission limit values should be foreseen that are more in line with those for heavy duty vehicles than the previous ones. 

In addition, the establishment of a suitable type of framework directive should be considered, regulating the periodical inspection of small combustion facilities EU-wide and, in case of emission limit value exceedances or for old facilities (e.g. PM10, NOx, CO, etc.), stipulating the obligation to maintain, renovate or replace an insufficient heating system. 

In some countries a national emission reduction plan according to Article 4 (4) of the LCP Directive [12] has been implemented instead of applying emission limit values for individual installations. High local concentrations at specific sites might therefore occur. As laid down in Article 10 of the IPPC Directive [13], stricter...

The most effective and advanced stages in the development of activities and their methods of operation. Indicate the practicable suitability of particular techniques for providing in principle the basis for emission limit values designed to prevent or, where that is not practicable, reduce emissions. 

Obviously, decision makers did not remain unconcerned, especially considering traffic emissions. The first regulation came into force by September 1971, a few months before the first earth summit the Stockholm conference. It was the starting point of a long sequence of amendment steps towards more and more stringent emission limit values, also associated with numerous technical standards (monitoring procedures, test cycle profiles, vehicle fleet typology,. ..). 

Emission limit values and continuous monitoring of CO and emission limit values for organic compounds. 

This example plant has a permitted emission limit value for dust of 10 mg/Nm . The monitoring system has an alarm limit of 5 mg/Nm . If this limit is passed, the filter is checked and tested with fluorescence material. If the measured value passes 10 mg/Nm , the production and filter are stopped. Calibration of the monitoring equipment is performed twice a year by an external contractor. 

The BAT chapter (Chapter 5) identifies those techniques that the TWG considered to be BAT in a general sense for the foundry industry, based upon the information in Chapter 4 and taking account of the Article 2(11) definition of best available techniques and the considerations listed in Annex IV to the Directive. The BAT chapter does not set or propose emission limit values but suggests emission levels that are associated with the use of BAT.

Expressed in mass of solvent emitted per kilogram of product cleaned and dried. The emission limit in Article 5(8) does not apply to this sector. The following exemption refers only to Greece the total emission limit value does not apply, (l)(2)(3) for period of 12 years after the date on which this Directive is brought into effect, to existing installations located in remote areas and/or islands, with a population of no more than 2000 permanent inhabitants where the use of advanced technology equipment is not economically feasible...

Emissive limit values are stipulated for plants covered under this directive for exhaust-gases in mgC/Nm as well as limits for diffuse emissions in % solvents input. If these data are not available, total emission limit values are used. 

Definition of Emission Limit Value The Emission Limit Value is understood as the mass of volatile organic compounds, the concentration, the percentage and/or the amount of emission - ascertained under normal conditions - expressed in certain specific parameters, which in one or several time periods must not be exceeded [EU-VOC-Richtlinie]. ...
