No national legislation; however, any company which is licensable under the Irish Environment Protection Act, and which is seen as having "dioxin emission potential," may be required to undertake dioxin emission measurements The Irish EPA BATNEEC Guidance Note for the Waste Sector includes a section on dioxin emissions, which states "The aim should be to achieve a guide TEQ value of 0.1 ng I-TEQ/m3. For hazardous waste incineration, subject to the EC establishing harmonized measurement methods by 01.07.96, this guide level becomes an emission level from 01.01.97"; where other issues arise, they tend to be guided by limits set or recommended by other EU countries (e.g., United Kingdom or Germany) 11/19/97 Regulates new municipal solid waste incinerator plant at the limit of 0.1 ng I-TEQ/m3 in the exhaust gas; existing incineration plant must be technically upgraded to meet the above emission limit 4/23/98 Implements a zero emission concentration of dioxins and other organic compounds into the Venice Lagoon National Toxicology Commission proposed, in 1985, PCDD and PCDF reference technical limits for land rehabilitation; for farmable land the reference value was 750 ng/m2 and for nonfarmable land 5,000 ng/m2; continued

APPENDIX A Food 253 In Force Description 12/6/98 10/7/98 1991 Maximum concentrations set for milk and dairy products: 5 pg 2,3,7,8-TCDD/g milk lipid for foods with > 2% lipid, 100 pg 2,3,7,8-TCDD/g food for foods with < 2% lipid Withdrawal of milk and milk products from the market when maximum dioxin concentration is exceeded The French Ministry of Agriculture recommended a maximum limit value of 5 pg I-TEQ/g lipid for milk and milk products; at this level products are removed from the market An objective has been established of achieving less than 1 pg I-TEQ/g lipid A maximum tolerable daily intake of 1 pg I-TEQ/kg body weight is recommended by Conseil Superieur d'Hygiene Publique of France In 1992 and 1993, a Joint Working Group of the Federal and Lander Ministers of the Environment on dioxins established recommendations and reference values for dioxin concentrations in soils and milk; for preventative reasons, and as a long-term objective, the dioxin concentrations in soil used for agricultural purposes should be reduced to below 5 ng I-TEQ/kg; cultivation of foodstuffs is not restricted if the soil contains 5-40 ng I-TEQ/kg, although it is recommended that critical land uses, for example grazing, should be avoided if increased dioxin levels are found in foodstuffs grown in such soils; the cultivation of certain feedstuffs and foodstuffs is restricted if the dioxin contamination is above 40 ng I-TEQ/kg soil; unlimited cultivation is allowed for plant with minimum dioxin transfer (e.g., corn). The recommended maximum dioxin concentration in milk should not exceed 5.0 pg I-TEQ/g milk lipid; thus, milk and dairy products should not be on the market if the contamination exceeds this value To reduce the human impact via consumption of dairy products, a limit value of 3 pg I-TEQ/g lipid was set The target concentration of 0.9 pg I-TEQ/g milk lipid was set as an objective to be achieved; if the TDI exceeds 10 pg I-TEQ/kg body weight (excluding PCBs) action should be taken to reduce the daily dioxin intake; a target value of 1 pg I-TEQ/kg body weight should be achieved Based on the TDI and on the inventory of food consumption, a standard of 6 pg I-TEQ/g lipid for milk and milk products was derived originally in 1989; the decision was taken that the standard should remain unaltered in 1991 The Ministry for Agriculture, Fisheries and Foods established a recommended maximum tolerable concentration of dioxins, furans, and dioxin-like PCBs in cows' milk; this is currently set at 0.66 ng TEQ/kg of whole milk (approximately 16.6 ng TEQ/kg of milk lipid) le daily
