    paragraph_quote: p. Onsite Sewage Disposal Systems (09/14/2015) i. Definition
      An Onsite Sewage Disposal System refers to wastewater systems designed to treat
      and dispose of effluent on the same Property that produces the wastewater. ii.
      Required Analysis and Reporting The Appraiser must note the deficiency of MPR
      or MPS and notify the Mortgagee if the Property is not served by an off-site
      sewer system and any living unit is not provided with an Onsite Sewage Disposal
      System adequate to dispose of all domestic wastes in a manner that will not
      create a nuisance, or in any way endanger the public health. The Appraiser must
      visually observe the Onsite Sewage Disposal System and its surrounding area.
      The Appraiser must require an inspection to ensure that the system is in proper
      working order if there are readily observable signs of system failure. The Appraiser
      must report on the availability of public sewer to the site. The Appraiser must
      note the deficiency of MPR or MPS and notify the Mortgagee if the Appraiser
      has evidence that the Onsite Sewage Disposal System is not sufficient. 4. Valuation
