Plans,specifications and MPCA approval are not necessary when maintenance dictates the need for installation of new equipment,provided the equipment is the same design size and has the same design intent. For instance, a broken pipe,lift station pump,aerator,or blower can be replaced with the same design-sized equipment without MPCA approval. If the proposed construction is not expressly authorized by this permit,it may require a permit modification. If the construction project requires an Environmental Assessment Worksheet under Minn.R.4410,no construction shall begin until a negative declaration is issued and.all approvals are received or implemented. 1.41 Report Changes..The Permittee shall give advance notice as soon as possible to the MPCA of any substantial changes in operational procedures,activities that may alter the nature or frequency of the discharge,and/or material factors that may affect compliance with the conditions of this permit.(Minn,.R.7001.0150,subp.3, item M) 1.42 Chemical Additives.The Permittee shall receive prior written approval from the MPCA before increasing the use of a chemical additive.authorized by this permit,or using a chemical additive not authorized by this permit, in quantities or concentrations that have the.potential to change the characteristics,nature and/or quality of the discharge.
