<s>[INST] The next text is a question of a member of the European parliament:"One example which illustrates that the IPPC Directive basically applies the approach adopted in Directive 84/360/EEC(1), involving water to industrial plants or processes but fails to incorporate important elements of the 1976 water Directive (76/464/EEC)(2), is the absence of the standstill principle, according to which the setting of emission standards may not run counter to the objective of the water Directive, i.e. it may not increase water pollution. The air Directive 84/360/EEC permits only an insignificant increase in air pollution. The proposed IPPC Directive does not refer to this. Another example is the degree of discretion which must be permitted in legislation on water management to safeguard the public water supply, in contrast to decisions taken under clean air legislation.        1.  In view of this, how is existing EU legislation on emissions into the air to be incorporated in water legislation?      2.  If it is to be incorporated, it is not necessary to improve integration, and in particular to amend the IPPC Directive, in order to take account of the interests and requirements of water management, for example, by including the standstill principle and allowing Member States discretion as regards water management in order to safeguard the public water supply?      (1)OJ No L 188, 16. 7. 1984, p. 20.  (2)OJ No L 129, 18. 5. 1976, p. 23."
