ORDER 

3. Defendant shall update its SWPPP to reflect the BMPs outlined above and include a 

stormwater monitoring plan and protocol. 

4. During precipitation events of greater than 0.2 inches, Defendant shall obtain samples from 

the following locations: 

(a) Three outfall pipes located on the south side of the Murieta Equestrian Center 

facility and just north of the Unnamed Stream; 

(b) The vegetated swale at the applicable point of discharge to the Unnamed Stream. 

(c) Notwithstanding anything in this Order to the contrary, Defendant shall not be 

required to: 

i. Obtain more than one set of samples from any single storm event. 

ii. Obtain more than two sets of samples in any calendar month. 

5. Defendant shall analyze samples taken pursuant to Paragraph 4 of this Order for Total 

Suspended Solids (TSS), E. coli, fecal coliform, and ammonia. Defendant shall deliver all 

such samples to a California-certified environmental laboratory for analysis within the 

allowable hold times, pursuant to 40 C.F.R. Part 136. 

6. Defendant shall update its SWPPP within 45 days following this Order and shall document 

all BMPs, inspection protocols, and sampling results to ensure compliance with these 

interim requirements. It shall be understood, however, that a single sample result shall not, 

in and of itself, constitute proof of an exceedance of any applicable standard. 

7. Defendant shall file with the court a status statement every thirty days describing all 

activities undertaken to implement the aforementioned obligations. Defendant shall attach 

to its initial status statement a copy of its Permit Application and all information submitted 

therewith. Defendant shall further attach to its initial and subsequent status statements 

copies of correspondence to or from the Regional Board or other regulatory agencies 

related to the Permit Application and processing and/or Defendant’s management of waste 

in conjunction with operation of the Murieta Equestrian Center, Defendant’s updated 

SWPPP, proof of interim BMP implementation, including photographs, and all laboratory 

reports related to stormwater sampling.
