<br />ALTERNATE LIMITATIONS
<br />Any discharge or increase in the volume of a discharge is caused by precipitation within any 24-hour period less than or
<br />equal to the 10 -year, 24-hour precipitation event (or snowmelt of equivalent volume) may comply with alternate
<br />limitations subject to burden of proof requirements as described in the EFFLUENT LIMITATIONS AND MONITORING
<br />REQUIREMENTS section.
<br />The following limits for Fe(TR) and Settleable Solids may be substituted for the Fe(TR) and TSS limitations contained in
<br />the previous table. All other parameters remain unchanged.
<br />Alternate Limits Outfalls 001, 009, 018, 022, 026 and 027 (less than or equal to the 10 -year, 24-hour
<br />precipitation event)
<br />ALTERNATE LIMITATIONS
<br />Any discharge or increase in volume of a discharge caused by precipitation within any 24-hour period greater than the
<br />10 -year, 24-hour event (or series of storms or snowmelt of equivalent volume) may comply with alternate limitations
<br />subject to burden of proof requirements as described in the EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
<br />section.
<br />The following limit for Fe(TR) may be substituted for that contained in the previous table. TSS and Settleable Solids
<br />monitoring/ effluent limitations are not required. All other parameters remain unchanged.

<br />Discharges authorized under this permit must be controlled as necessary to meet applicable water quality
<br />standards.
<br />The division expects that compliance with the other terms and conditions in this permit will control discharges as
<br />necessary to meet applicable water quality standards. If at any time the permittee becomes aware, or the division
<br />determines, that the authorized discharge causes or contributes to an exceedance of applicable water quality
<br />standards, the permittee must take corrective action as required, document the corrective actions as required,
<br />and report the corrective actions to the Division as required (see CORRECTIVE ACTIONS).
<br />If the division becomes aware of information indicating that compliance with the other terms and conditions of this
<br />permit will not control the discharge as necessary to meet applicable water quality standards, the division may
<br />include additional site-specific water quality -based effluent limitation(s) to the discharge.
