Page | 5 <br /> <br />Is participation in the IAIA a requirement? What happens if Orange County does not <br />participate in the IAIA? <br />Participation in the IAIA is not a requirement, but if a jurisdiction chooses not to participate, it <br />will be on its own to comply with the requirements under the current Strategy. Stage I <br />compliance without the IAIA would require installation of nutrient removing measures (i.e. <br />SCMs and other methods) in direct relation to Orange County’s prior nutrient loading. <br />Stage I compliance under the IAIA would be based upon expenditures at an agreed upon <br />amount, which is currently expected to be $161,943 for Orange County. If Orange County <br />chooses not to participate in the IAIA, Orange County would need to meet Stage I compliance <br />via the self‐funded installation of enough nutrient‐reducing ponds or similar SCMs to <br />compensate for the amount of Nitrogen and Phosphorus added to Falls Lake (from Orange <br />County) between 2006 and 2012. Orange County staff has previously calculated the required <br />nutrient reduction amount to be approximately 5,900 lbs of Nitrogen and 450 lbs of <br />Phosphorus – with estimated compensatory costs ranging between $49,792 and $46,057,600. <br />An important difference is that the IAIA will explicitly allow credit for land conservation efforts, <br />of which Orange County has and plans considerable commitment. At present, there is no credit <br />for land conservation under the adopted Rules, although the State is reassessing this as a <br />measure. If the IAIA was not chosen, as things currently stand the entire allotment of nutrients <br />would need to be reduced with traditional SCMs (ponds, permeable pavement, green roofs, <br />etc). However, with the IAIA compliance is accomplished through the financial commitment of <br />$161,943 to include expenditures on land conservation, which may emanate from multiple <br />funding sources. <br /> <br /> <br />In conclusion, Orange County staff believes that strength and voice is much greater in numbers, <br />and that taking on the Stage I compliance task by ourselves may be a difficult and potentially <br />much more costly approach. Staff believes that continuing our partnership with the UNRBA <br />and participating in the IAIA will allow Orange County to meet Stage I compliance requirements <br />in an organized and financially efficient manner, while also better positioning Orange County <br />for future (pending) Stage II compliance requirements. <br />8
